I was wondering if someone has a solution to the problem I've been having with TextEdit (I'm using it on a MacBook Pro, 10.7.5): at least twice per day I get the message that a document I'm working on "could not be autosaved" - after that, unless I quite TextEdit and reopen it I cannot save anything. Given how often it happens, it's really become quite annoying. I've tried searching for solutions online but haven't found anything applicable so far. Any ideas??
