I have a procedure that adds new toolbars to a users current menu file. It ends with: aToolbarGroup.Save acMenuFileSource ThisDrawing.Application.Update Everything works perfectly except, the user must restart AutoCAD for the toolbar macros to work. The toolbars, buttons, button images and every other feature is fine. It's just that the macro string associated with the button doesn't run. Once AutoCAD is restarted everything works. Any suggestions?
