>This nis puire conjecture for me. I ahve observed some strange interactions between grids and forms especially when using a combo within the grid. This behavior leads me to suspect that grids track their recordsource independent of the form's data session.

A browse simply puts a display on the data in a work area outside the browse. Therefore a browse does not need to process all of the records before showing the visible ones.

Jim,

I am observing random "cannot access selected table" error messages when closing forms having view based combos within a grid. I am pretty sure focus is not redirected to the combo and there's no refresh either. I've come to think this is a session thing. It does not happen much on NT4, but much more on WIN 2000. Do you refer to this type of "interaction"?
