This doesn't sound right.
For now, call the CalculateFields method of the dataset in the OnExit event
of the control.
If you have time, please send me a quick and easy sample of the problem.

Subject: [IBO] TIB_Query's OnCalculateEvent

> OnCalculateField event is fire when I enter and start typing into the
TIB_Edit control but not when I exit the control and the value is changed.
Is this correct behaviour or I miss something ?

I'm using Delphi 5 + IBO 4.2Fm + Firebird Beta2.
