I've got this problem for a long time.

There is a combo Box in my grid. The grid's rowsource property is based on a VIEW. The combo box rowsource property is also based on a view. Now, sometimes, when I add a new record on a grid, and I try to pick an item in the combo box, the combo box does not open. But, some other times, I can... This is happening only in the grid.
The size of the combo box list is about 700 records...
