Hi,

For&nbsp;the&nbsp;functions&nbsp;like&nbsp;EditOverlay\_FeatureDragging&nbsp;(FeatureResizing&nbsp;etc&nbsp;etc)..&nbsp;&nbsp;if&nbsp;the&nbsp;Cancel&nbsp;flag&nbsp;is&nbsp;set&nbsp;in&nbsp;the&nbsp;event&nbsp;a&nbsp;null&nbsp;reference&nbsp;exception&nbsp;is&nbsp;thrown.

We&nbsp;need&nbsp;this&nbsp;to&nbsp;prevent&nbsp;shapes&nbsp;overlapping,&nbsp;so&nbsp;we&nbsp;set&nbsp;this&nbsp;e.Cancel&nbsp;to&nbsp;true&nbsp;when&nbsp;we&nbsp;detect&nbsp;the&nbsp;moved&nbsp;shape&nbsp;overlaps.&nbsp;Is&nbsp;there&nbsp;something&nbsp;we&nbsp;missed,&nbsp;or&nbsp;is&nbsp;this&nbsp;a&nbsp;bug?

Regards

Gordon
