&nbsp;&nbsp;  
&nbsp;No&nbsp;exception&nbsp;in&nbsp;singlethead.&nbsp;  
&nbsp;I&nbsp;doubt&nbsp;that&nbsp;it’s&nbsp;the&nbsp;same&nbsp;bug&nbsp;that&nbsp;the&nbsp;one&nbsp;you’re&nbsp;talking&nbsp;and&nbsp;it’s&nbsp;not&nbsp;the&nbsp;same&nbsp;exception&nbsp;and&nbsp;not&nbsp;the&nbsp;same&nbsp;behaviour.&nbsp;  
&nbsp;&nbsp;  
&nbsp;My&nbsp;bug&nbsp;seems&nbsp;to&nbsp;be&nbsp;related&nbsp;to&nbsp;the&nbsp;tiling/preview&nbsp;tiling&nbsp;system&nbsp;and&nbsp;french&nbsp;OS&nbsp;enviroment.&nbsp;  
&nbsp;&nbsp;  
&nbsp;This&nbsp;occurs&nbsp;when&nbsp;users&nbsp;are&nbsp;panning/zooming&nbsp;as&nbsp;you&nbsp;can&nbsp;see&nbsp;in&nbsp;the&nbsp;exception&nbsp;trace.&nbsp;  
&nbsp;&nbsp;  
&nbsp;Please&nbsp;let&nbsp;me&nbsp;know&nbsp;as&nbsp;soon&nbsp;as&nbsp;it’s&nbsp;fixed.&nbsp;  
&nbsp;&nbsp;

&nbsp;

Patrick,  
&nbsp;  
Thanks&nbsp;for&nbsp;your&nbsp;more&nbsp;information!&nbsp;No&nbsp;exception&nbsp;in&nbsp;singlethead&nbsp;is&nbsp;a&nbsp;proof&nbsp;of&nbsp;the&nbsp;bug&nbsp;which&nbsp;fixed&nbsp;in&nbsp;3.1.302.  
&nbsp;  
Have&nbsp;you&nbsp;ever&nbsp;disable&nbsp;the&nbsp;preview,&nbsp;if&nbsp;throw&nbsp;exception&nbsp;still,&nbsp;that&nbsp;means&nbsp;the&nbsp;bug&nbsp;is&nbsp;not&nbsp;related&nbsp;to&nbsp;preview,&nbsp;in&nbsp;this&nbsp;condition,&nbsp;maybe&nbsp;you&nbsp;can&nbsp;try&nbsp;the&nbsp;3.1.302.  
&nbsp;  
I&nbsp;tested&nbsp;3.1.302&nbsp;in&nbsp;multithread,&nbsp;it&nbsp;has&nbsp;not&nbsp;any&nbsp;exception&nbsp;if&nbsp;I&nbsp;do&nbsp;any&nbsp;operation.  
&nbsp;  
If&nbsp;still&nbsp;can&nbsp;not&nbsp;find&nbsp;your&nbsp;problem,&nbsp;maybe&nbsp;you&nbsp;can&nbsp;make&nbsp;a&nbsp;small&nbsp;sample&nbsp;to&nbsp;reproduce&nbsp;this&nbsp;bug,&nbsp;I&nbsp;think&nbsp;that’s&nbsp;the&nbsp;best&nbsp;and&nbsp;fast&nbsp;way&nbsp;to&nbsp;find&nbsp;the&nbsp;bug.  
&nbsp;  
Thanks  
James

The&nbsp;2&nbsp;issues&nbsp;occurs&nbsp;when&nbsp;I&nbsp;play&nbsp;(scroll/pan)&nbsp;with&nbsp;the&nbsp;map&nbsp;in&nbsp;multithread&nbsp;environment&nbsp;with&nbsp;preview&nbsp;tiles&nbsp;on.&nbsp;  
&nbsp;in&nbsp;single&nbsp;thread&nbsp;and&nbsp;without&nbsp;preview&nbsp;tile,&nbsp;with&nbsp;the&nbsp;same&nbsp;data,&nbsp;it&nbsp;works&nbsp;well.&nbsp;  
&nbsp;&nbsp;  
&nbsp;I’m&nbsp;using&nbsp;decimaldregrees&nbsp;data,&nbsp;projected&nbsp;to&nbsp;meters&nbsp;and&nbsp;displayed&nbsp;with&nbsp;map&nbsp;control&nbsp;unit&nbsp;to&nbsp;meter.&nbsp;  
&nbsp;&nbsp;  
&nbsp;I’m&nbsp;pretty&nbsp;sure&nbsp;that&nbsp;there&nbsp;is&nbsp;an&nbsp;issue&nbsp;somewhere&nbsp;in&nbsp;your&nbsp;tiling&nbsp;system&nbsp;;&nbsp;I&nbsp;can&nbsp;reproduce&nbsp;it&nbsp;very&nbsp;easily&nbsp;but&nbsp;only&nbsp;in&nbsp;multithread+previewtile&nbsp;mode.&nbsp;  
&nbsp;Remember&nbsp;that&nbsp;I’m&nbsp;french&nbsp;and&nbsp;the&nbsp;issue&nbsp;maybe&nbsp;related&nbsp;to&nbsp;my&nbsp;locale.&nbsp;  
&nbsp;&nbsp;  
&nbsp;add.&nbsp;info,&nbsp;I&nbsp;set&nbsp;map.minscale&nbsp;=&nbsp;10;&nbsp;I&nbsp;don’t&nbsp;know&nbsp;if&nbsp;it’s&nbsp;related&nbsp;  
&nbsp;Add.&nbsp;info2&nbsp;:&nbsp;I&nbsp;can&nbsp;also&nbsp;reproduce&nbsp;case&nbsp;where&nbsp;one&nbsp;tile&nbsp;is&nbsp;missing/misplaced/misaligned&nbsp;when&nbsp;displaying;&nbsp;again&nbsp;only&nbsp;in&nbsp;multithread+preview&nbsp;only&nbsp;  
&nbsp;&nbsp;

&nbsp;&nbsp;  
&nbsp;Thanks&nbsp;for&nbsp;your&nbsp;post.&nbsp;  
&nbsp;&nbsp;  
&nbsp;We&nbsp;have&nbsp;already&nbsp;created&nbsp;a&nbsp;virtual&nbsp;machine&nbsp;which&nbsp;using&nbsp;French&nbsp;environment&nbsp;instead&nbsp;of&nbsp;English&nbsp;environment.&nbsp;That&nbsp;machine&nbsp;has&nbsp;recreated&nbsp;many&nbsp;issues&nbsp;before,&nbsp;some&nbsp;of&nbsp;them&nbsp;are&nbsp;solved,&nbsp;and&nbsp;some&nbsp;of&nbsp;them&nbsp;are&nbsp;not.&nbsp;But&nbsp;this&nbsp;time,&nbsp;I&nbsp;can&nbsp;not&nbsp;recreate&nbsp;the&nbsp;exception,&nbsp;I&nbsp;follow&nbsp;the&nbsp;setting&nbsp;as&nbsp;you&nbsp;mentioned:&nbsp;use&nbsp;multi-threaded&nbsp;mode,&nbsp;turn&nbsp;on&nbsp;preview,&nbsp;project&nbsp;data&nbsp;from&nbsp;decimal&nbsp;degree&nbsp;to&nbsp;meter&nbsp;unit,&nbsp;set&nbsp;MapUnit&nbsp;to&nbsp;meter,&nbsp;set&nbsp;mini&nbsp;scale&nbsp;to&nbsp;10.&nbsp;&nbsp;  
&nbsp;&nbsp;  
&nbsp;So&nbsp;if&nbsp;you&nbsp;could&nbsp;provide&nbsp;a&nbsp;small&nbsp;and&nbsp;simple&nbsp;sample,&nbsp;it&nbsp;will&nbsp;be&nbsp;very&nbsp;helpful&nbsp;to&nbsp;recreate&nbsp;this&nbsp;problem&nbsp;and&nbsp;solve&nbsp;it.&nbsp;  
&nbsp;&nbsp;  
&nbsp;I&nbsp;am&nbsp;sorry&nbsp;about&nbsp;the&nbsp;problem&nbsp;of&nbsp;info2,&nbsp;to&nbsp;be&nbsp;frank&nbsp;they&nbsp;were&nbsp;the&nbsp;known&nbsp;issues&nbsp;which&nbsp;we&nbsp;could&nbsp;not&nbsp;solve&nbsp;recently,&nbsp;if&nbsp;another&nbsp;users&nbsp;mentioned&nbsp;this&nbsp;problem,&nbsp;we&nbsp;will&nbsp;let&nbsp;them&nbsp;use&nbsp;single-threaded&nbsp;temporary&nbsp;until&nbsp;we&nbsp;solve&nbsp;it.&nbsp;I&nbsp;am&nbsp;so&nbsp;sorry&nbsp;given&nbsp;you&nbsp;so&nbsp;many&nbsp;inconveniences,&nbsp;I&nbsp;am&nbsp;sure&nbsp;that&nbsp;if&nbsp;we&nbsp;fix&nbsp;it&nbsp;I&nbsp;will&nbsp;let&nbsp;you&nbsp;know&nbsp;as&nbsp;soon&nbsp;as&nbsp;possible.&nbsp;

&nbsp;

Patrick,  
&nbsp;  
Your&nbsp;sample&nbsp;code&nbsp;can&nbsp;not&nbsp;work&nbsp;because&nbsp;it&nbsp;will&nbsp;throw&nbsp;exception&nbsp;at&nbsp;the&nbsp;penultimate&nbsp;line&nbsp;of&nbsp;code:&nbsp;  
winformsMap1.CurrentExtent&nbsp;=&nbsp;worldLayer.GetBoundingBox();  
&nbsp;  
The&nbsp;reason&nbsp;is&nbsp;that&nbsp;the&nbsp;worldLayer&nbsp;is&nbsp;not&nbsp;Open.&nbsp;  
&nbsp;  
We&nbsp;can&nbsp;easily&nbsp;add&nbsp;worldLayer.Open()&nbsp;to&nbsp;make&nbsp;your&nbsp;sample&nbsp;code&nbsp;works,&nbsp;but&nbsp;I&nbsp;am&nbsp;afraid&nbsp;this&nbsp;code&nbsp;might&nbsp;not&nbsp;the&nbsp;original&nbsp;one&nbsp;which&nbsp;will&nbsp;throw&nbsp;the&nbsp;exception&nbsp;in&nbsp;FR&nbsp;not&nbsp;in&nbsp;EN.&nbsp;Could&nbsp;you&nbsp;review&nbsp;the&nbsp;code&nbsp;and&nbsp;verify&nbsp;it?  
&nbsp;  
I&nbsp;can&nbsp;not&nbsp;recreate&nbsp;your&nbsp;problem&nbsp;so&nbsp;far,&nbsp;sometimes&nbsp;it&nbsp;will&nbsp;very&nbsp;easy&nbsp;to&nbsp;solve&nbsp;the&nbsp;problem&nbsp;if&nbsp;we&nbsp;can&nbsp;recreate&nbsp;the&nbsp;problem&nbsp;easily,  
So&nbsp;could&nbsp;you&nbsp;provide&nbsp;a&nbsp;more&nbsp;certainly&nbsp;sample,&nbsp;for&nbsp;example,&nbsp;if&nbsp;I&nbsp;click&nbsp;a&nbsp;button,&nbsp;the&nbsp;exception&nbsp;will&nbsp;be&nbsp;thrown.&nbsp;I&nbsp;remember&nbsp;you&nbsp;have&nbsp;provided&nbsp;a&nbsp;sample&nbsp;about&nbsp;tile&nbsp;cache,&nbsp;if&nbsp;I&nbsp;click&nbsp;the&nbsp;button,&nbsp;it&nbsp;will&nbsp;generate&nbsp;cached&nbsp;images&nbsp;in&nbsp;specific&nbsp;folder,&nbsp;in&nbsp;French&nbsp;environment,&nbsp;the&nbsp;double&nbsp;contain&nbsp;‘,’&nbsp;so&nbsp;the&nbsp;folder&nbsp;name&nbsp;is&nbsp;not&nbsp;as&nbsp;we&nbsp;expected,&nbsp;when&nbsp;we&nbsp;recreate&nbsp;the&nbsp;problem,&nbsp;at&nbsp;the&nbsp;same&nbsp;time,&nbsp;we&nbsp;solve&nbsp;the&nbsp;problem.  
&nbsp;  
I&nbsp;will&nbsp;keep&nbsp;testing&nbsp;it,&nbsp;and&nbsp;if&nbsp;I&nbsp;make&nbsp;any&nbsp;progresses&nbsp;I&nbsp;will&nbsp;let&nbsp;you&nbsp;know.
