Hello, everyone

I have combo box as a current control of a column in a grid control of a form.
The properties of the grid control are set as follows:
RecordSourceType = 1&& Alias
RecordSource = 'B' && Table B
Columns = 2
Columns(1).controlsource = 'B.f3' && the field type is "I"nteger.
Columns(2).controlsource = 'B.f4' && the field type is "N"umeric.

The combo box belongs to Columns(1).
The properties of the combo box are set as follows:
Rowsourcetype = 2 &&Alias
Rowsource = "A.f1, f2" && Table A, field f1, field f2; f1 is type "C"haracter and f2 "I"nteger.
BoundColumn = 2
BoundTo = .t.
Controlsource = "B.f3" && is set by it's parent

When a user changes the value of combo box, it updates the value of "B.f3".
The problem is that whenever the combo box GotFocus, the selection of the combo box disappears. When it looses focus, the selection reappears.

Does anybody know why? Any help will be appreciated!
