Problem description : In Solidworks 2013 (and 2014), right clicking on a part or feature in the model tree brings up a popup menu with several options, when I move my mouse to the top portion of the popup menu options, it disappears before I can click on any of the buttons. The problem goes away when I exit coherence mode. I've played with several of the coherence, display and performance options, nothing makes a difference, only turning off coherence. Does anyone have any suggestions?
