CorelDraw 12 (and X3, and probably other versions) crashing with TweakUI

Important safety tip: Don’t disable anything in the “Common Dialogs” section of TweakUI for Windows XP if you also use CorelDraw 12 or X3. Disabling “Enable AutoComplete” and “Remember previously-used filenames” caused CorelDraw 12 and X3 to crash whenever they displayed a File-related dialog box. Reinstalling CorelDraw had no effect on the crashes nor did upgrading to the latest service pack of X3. Corel-PAINT was also affected. I hate computers.
