There must be an underlying code in the Valid, InteractiveChange, of Click event of the combobox. The behaviour seems related to commands like SEEK, GOTO or something that forces the pointer to move.

>I have two tables....
>
>table #1: bar
>number = integer (unique)
>descrip = text
>
>table #2: disp
>number = integer (unique)
>barnum = integer (number from table #1)
>
>I created a grid on the DISP table. I added a combo for the barnum. I set the rowtype to 6-Fields and the
>rowsource to bar.descrip,number. I set the bound=.t. and the bound column=2
>
>I set the column to control=combo1, control source=barnum
>
>I also have both tables listed in the DE without any relationship between them.
>
>The principle is to enter a disp # and pick the associated bar from the combo box made up of the
>descrips.
>
>I either get a hit/miss on the data being in the combo. Or, like right now, if I go and try to pick a bar name,
>the combo "expands" while I hold the mouse down. As soon as I release it (like to go and pick a
>selection), the combo closes and my table jumps to the LAST record in the DISP table.

>This should be a simple grid but I HATE GRIDS and THEY HATE ME!!!!!
