Getting "Not responding" error when saving

So, I'm not sure why but, recently when I choose to save a Model,Assembly or Drawing I have been experiencing the nasty "Not Responding" error message in the menu bar.This results in a complete shut-down of the SolidWorks app. Starts back up and then runs fine.

It's been almost a year since purchasing 2011 professional on a new work station and has been running very well until about a week ago. This saving error seems to be getting worse.

If anyone as any ideas, I'd like to hear them, It's starting to make things a little UN-productive.

Thanks for any help!
