When having a call to Blender.Window.EditMode() inside a redraw scriptlink I encounter the following error when trying to enter editmode:
RuntimeError: internal error - update_armature_weakrefs
It seems related to this bug.
Can anyone confirm this bug? I’m on windows XP home with the official blender 2.43 windows build.
To test it open the following .blend file, and try to go into editmode using the tab-key. You’ll find the error in the console.
