What were you doing in Maya just before it crashed. Sometimes it can be a history build up. I had a problem where every time I tried to delete history on a smooth mesh (hotkey 3 on the keyboard) it caused Maya to stop working, had to go back to low res, delete history, then smooth res. Dear MrYeti! I were modeling a mushroom before it crashed. I just hit hotkey 1-2-3-4-5 to change model. Let me try what your suggestions. Thanks so much
