Ramon If you think Animation master hangs itself to easy(which I fully agree with) then there is a tutorial at AM tutorial resources that teach you some stuff to avoid. I have been going crazy many times over this software and I have wanted to forget it and blow it in the air. But patience seems to pay of....
This is taken from the tip page
"Things that can be done to avoid hanging:
1) Try to not have more than one window open at a time -and if you must, maximize them so that they don't overlap - or if you have two open simultaneously, use the "Tile" commands under the Windows menu item to make sure they're using up the screen space.
2) Don't use the tabbed "Workbook" mode.
3) Save often, and it's a good idea to save versions. Tyler told me he can easily go through the alphabet in a day of working on a model (Bottle_a.mdl, Bottle_b.mdl, etc). I tend to save after every major change, and I don't see crashing nearly as much as I used to.
4) Use Undo with patience - in 10, it's actually pretty good. I still save versions, though....
5) One key is *patience* - let the software catch up to you, and if you make it through a huge copy/paste or Undo, save your model immediately. One thing I can thank AM for, is my vastly improved "Save Discipline" in all the software I use......
6) AM is a memory and CPU hog. Don't run it simultaneously with another memory hog - like Maya, Max, or Photoshop - *expecially* if you don't have a ton of memory (512 MB or more). I try not to run it with anything going in the background (except Winamp, maybe
7) Of course, make sure that your drivers are updated, etc, etc."
I know it shouldnt be like this at all, we all want stability! But if you learn where the pits are it will be much easier using AM.
