I am working on an application in VB .net 2008 which worksfine aside from this issue. If I have an assembly or part open,Realview on, the part needs saving (*), and I save the fileSolidWorks crashes. I can catch the FileSaveNotify events but bythat point it is too late and SW crashes anway. Anyone see anythinglike this?SolidworksApi macros
