Using 2010. I've got a combo box on a continuous subform that is based on a value list. When I attempt to select an item from the list, the list briefly drops down then disappears. I have to select it again. The list willdrop down a second time and allow me to select an item. If I type the value in, rather than try to select it from the list, then the list does not disappear. This is very annoying.

FWIW, the combo is bound to the subform's recordsource.

Any idea why this list would disappear like this? Thanks for any help or advice.

I would try and delete the combobox and put it back in. The software isn't perfect. Things like that have happened to me before. So I would try that first.
