Removing the "Recent Documents" from the File Menu temporarily fixes this issue so you don't have to clear the menu all the time. This is obviously not a real fix, but it gets people back to work:
Tools > Customize
Choose Menu > "File"
Select "Recent Documents" and click "Modify" on the right pull down and choose "Delete"
Temporary fix until bug is solved:
