>It does sound like it might be the editbox making the change then. Try removing it as the control source for the edit box and see if the field state still changes. Otherwise, add a watch for GetFldState("YourField","YourTable") and set a breakpoint on it to see what is actually making the change.

I'll try to check it although I already fixed the problem. The EditBox class had no custom code at all. I have a feeling it's something internal wrong with GetFldState as even after I returned .f. from RecordChanged method the update was still firing (I originally had buffering mode 3 set for the view). Only after I changed Buffering mode to 5 and also made a change in RecordChanged method for this form to compare original record with current record it stopped calling the UPDATE. Also, OLDVAL and CURVAL returned the same values.

Wondering if anyone else can reproduce a problem.
