Thats awful! I know sometimes when I used to draw on the computer, I'd spend about 3 hours on a piece, then go to save it and have it freeze or get an error and close itself. -_-

Thank god for the auto save every 5 minutes now...

I'm so sorry it happened to you though. It has GOT to be one of the most frustrating things ever! @

Save often.

Programs like to freeze when they've been running for a while and have a high mem usuage.

Thats why whenever i have to do a keyboard shortcut in PS i'll go ahead and save (ctrl+s) just for good measure.
