Issue I517 [gui,defect,resolved] Conditional crash on entering View. On certain rare conditions, SIMION may crash on entering the View screen. It likely only occurs if View was previously exited in a non-2D view, the PA size decreased, and the mouse cursor is at certain locations over the PA when re-entering the View. To reproduce: Create a blank 400x400x400 array. Enter View. Switch to 3D Iso view. Hover mouse cursor over PA for a few seconds. Exit View. Remove All PAs from RAM. Create a blank 100x100x100 array. With mouse cursor in center of window, enter View (with keyboard shorcuts "V"). It then immediately crashes (sometimes). Reported by pypdjl-20081015 and an anonymous user-20080918 via crash reports.
