1) I load a project (nothing fancy: 70k triangles, 1.6GB textures);
2) I work on it a bit, do some mocap, previewing things, no big deal;
3) I save the project and open a new one with "open project" command;
4) iClone slows down, then goes stuck in some "saving undo/read data" process;
5) after 5-10 seconds shuts down.
 Happens almost ever, with different projects, after some work done (so it does NOT happen if repeatedly open new projects without working them).

Any suggestion?

Thanx a lot!
