CorelDRAW X6 :: 6.2 Update Now Produces Documents Could Not Be Closed Error?

Been running X6 for a month now.  Updated to 6.1.

Things have been fine until I updated to 6.2.

I will create artwork in Corel Draw, save it and then export some elements out to another format.

Then I try to close the drawing and exit.

CANNOT DO EITHER.

I get an error that says 'Some of the documents could not be closed because some tasks..background.  See status bar for....'

What the heck is going on here?  I cannot close the file.  I cannot exit the program.  The only way to get out of Corel Draw is to end the program through Task Manager.

This update is bad news.  I don't know how to go back to 6.1.
