Hi&nbsp;Klaus,&nbsp;  
&nbsp;&nbsp;  
&nbsp;Just&nbsp;tested&nbsp;it&nbsp;with&nbsp;a&nbsp;simple&nbsp;sample,&nbsp;hooked&nbsp;up&nbsp;the&nbsp;DrawTilesProgressChanged&nbsp;event&nbsp;of&nbsp;WorldMapKitWmsWpfOverlay&nbsp;and&nbsp;output&nbsp;the&nbsp;percentage.&nbsp;It&nbsp;always&nbsp;gets&nbsp;to&nbsp;100.&nbsp;  
&nbsp;&nbsp;  
&nbsp;So&nbsp;is&nbsp;this&nbsp;sample&nbsp;too&nbsp;simple&nbsp;to&nbsp;reproduce&nbsp;the&nbsp;issue?&nbsp;If&nbsp;it&nbsp;is,&nbsp;please&nbsp;let&nbsp;us&nbsp;know&nbsp;how&nbsp;to&nbsp;reproduce&nbsp;it&nbsp;more&nbsp;specifically.&nbsp;  
&nbsp;&nbsp;  
&nbsp;Regards,&nbsp;
