Autosave option?

Just spent a few hours finishing up my first takeoff and the program crapped out and closed, losing everything I'd done for the last few hours since I manually saved something.  Is there an autosave function I've missed?  And if not, why isn't their one so the crashes don't destroy hours of work?

Also, my mouse can't manipulate the screen - always have to use the keyboard or onscreen arrows.  Anything I'm missing to get the mouse to activate the screen by dragging like it does with other programs? Tutorials all show the mouse working properly. First time I've ever encountered my mouse not working as it should.
