Yea, I didn't want to make a big deal out of it, but the up/down button change did not fix the issue. In fact I'd say no impact positive or negative. It seems to happen when there is additional drawing 'complexity' in co-occurrence with the pop up drawing area. I.e. the pop up menu is drawing where arrows are drawn or error highlighting is occurring etc. Also maybe when the pop up menu area is near the 'edge' of the Dr window and or pane area. But again the problem is not consistently reproducible yet happens more often then not. Its not a once in a blue moon that thing. Sometimes an attempt to right click pop up menu will fail numerous times in a row then succeed for no apparent reason. <div class="gmail_quote">On Dec 4, 2012 9:07 PM, "Robby Findler" <<a href="mailto:robby@eecs.northwestern.edu">robby@eecs.northwestern.edu</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> On Tue, Dec 4, 2012 at 6:11 PM, Stephen Chang <<a href="mailto:stchang@ccs.neu.edu">stchang@ccs.neu.edu</a>> wrote: > On Fri, Nov 2, 2012 at 9:33 PM, Robby Findler > <<a href="mailto:robby@eecs.northwestern.edu">robby@eecs.northwestern.edu</a>> wrote: >> I've pushed a fix to this.
