HELP!!!

I am getting the dreaded message- An illegal operation has been performed. The application will be terminated.

The details screen tells me that the error is an invalid page fault in VFP.EXE.

The error occures when I am bringing up a screen and issue a requery.

The code involved is:

SELECT cView
REQUERY()


The view is a parameterized view with the paramater value set.

What will cause this behavior?
