Error - can't open, view or design reports

I'm using Access 2003 on Windows XP. I have never had a problem using the
reports functions before, and all of a sudden today, I go to use my databases
and I can no longer use any report functions (New, Design, View). It must be
the program doing this and not the databases because it is happening with all
dbs. The error message I get when I try to launch a report from a command
button is this:

"This action can't be carried out while processing a form or report event."

When I try to open or view a report from the main window report list, it
does not even give me an error message. When I click it just does nothing!!
HELP!
