Nadya:

I agree with you on that, but only when I am incharge, right now I am not so I can't changed unless like now that is a real problem in VFP8.0.

Regarding remove the code, I did that for the doscroll(), but if I dont get the focus in the grid the search functionality of the grid is not fired.

Can be posible that I send you the form file and the combo box class. That way you can see other areas.

I was thinking that the cause for the Fatal Error was an invalid index or data table that was not completely updated because I have table buffering on. But even in buffering off happening.
