I am experiencing a problem with wordperfect 12,the feature document compare keeps on getting corrupt. This application is installed on a windows xp OS,with SP2. I've tried uninstalling and reinstalling, but no luck. I have also tried rebuilding the entire PC,but no luck. It works fine when it is first installed, but when the user logs off, or reboots,or shuts down wordperfect gets corrupted. Does anyone have any ideas?
