post your code in the activate of the page - usually this can be fixed by setting the grid recordsource to "" before you define the grid and then making sure you go through the clean define if the cursor disappears for any reason (gets reloaded or deleted an recreated from a secondary sqlexec() query or something).

Something in your base code or is maybe resetting the grid's properties which is wiping out the recordsource?

Put a break on one of the cursor's disappearing or one of the grid's recordsource changing and see where it stops.
