Interactive Services Detection problem

I tried to create a .pdf file and save it to the desktop in VISTA. That
wasn't a good idea, now it keeps popping up telling me that Interactive
Services Dialog Detection needs to show me a message. When I click to show
the message it is the same save file window for the .pdf operation. If you
cancel it shuts the window and returns to windows. If I select a folder and
name for the file and click to save it, it shuts the window and returns to
windows. Within 5 minutes the same ISDD window comes up again.

Can this be shut off or stopped?
