I do not know what happened.  All was going quite well.  The demo Friday was excellent...no errors in the presentation.  One of the users suggested that I reimport our part data so that the two systems are synchronized on Monday.  No problem.  I had the SQL script ready to fire in that event. 

Last night I ran the import.  No problems.

Today, users are sending me lots of error windows.  In my initial investigation, I ran across a problem with the image field in the part table.  It was working fine before, but now it won't handle null data.  This just doesn't make sense.  I ran the DevEx update to the most recent control suite and also reset the Inherited UI project.  No problems with that; however, that makes no difference. 

What could I have done to mess up my image handling?

Thanks!
