To ask a question of John you go here
http://support.microsoft.com/newsgroups/default.aspx
From teh panel at right choose English then Home Publishing Then Picture It and you can ask your question.
The first things he will tell you to do are:
Run Scandisk to check for corruptions and errors (all Windows OS have this so check your help file sif you dont know ho wto run it.)
If that doenst help then Uninstall - do a disk clean up and degrag and run scandisk and then reinstall DIP.
If that doesnt help then he may be able to make other suggestions.
