Corel X5 creates LOTS of temp files

The new Corel X5 (with patches applied) is leaving lots of temp files in the Windows 7 local drive user\AppData\Local\Temp directory. By lots I mean hundreds of files that don't always go away when Corel is closed. As a result, I'm crashing on a regular basis in Corel. Sometimes the crash even corrupts the file. Is anyone else experiencing this difficulty? Does anyone have any suggestions about how to fix it?
