I am having this issue that every time when I am editing the custom properties from a part, then when I click the check mark to close it, it crashes!  this ONLY happens when I open the part from the drawing.  but if I just open the part itself, it is fine. it won't crash.. please help, if any of you have this same issue, and have a solution it will be highly appreciated

I am running VMware Fusion with Windows 7 Professional. using Solidworks 2011 SP5.0  please see attached machine specs.
