Error upon closing: Coreldraw x7 has stopped working

I am one of the folks who consistently gets the "Coreldraw x7 (64-bit) has stopped working" error message; however it is upon CLOSING the program that I get it. For the most part, basic edits apply without issue (knock on wood) although I like many others have had the intermittent crash. I am not a "power" user with Corel products, however, and don't even bother with lenses, transparencies, and fancy fills.

So, any info on why this is happening? Yes, I've uninstalled and reinstalled and applied all updates...

Thanks for any assistance.

Jenn.
