How do I get rid of this? I'm using a drawing program that can't save, and the most I can postpone the restart to is 4 hours. I need to sleep, and go to class, and go to work, and I'd like to postpone the important update or whatever for a few days until I finish my drawing.

If I leave it for more than 4 hours then it'll automatically restart and I'll lose all my work... all the layers and everything = pain in the arse.
