Ok, I think I've isolated the issue. The problem occurs whenever I choose to open the file via the welcome startup screen, the one that gives you the open to view the essential skills. If I close the startup screen without opening a file, I can click on the M menu, open the file, and everything is fine.
Could someone else try and see if they can reproduce this problem?
- Make sure that the welcome screen loads on startup (Help > Essential Skills Movies... > tick the box to show Welcome screen on startup)
- Close and reopen 3ds Max (I have 3ds Max Design 2013)
- Open a recent file from the Welcome screen
- See if you can click on the M menu
The file I'm working on is really big, so I wonder if that has anything to do with it.
