>I still have one other problem with these combo boxes. I have four combo boxes on this container - three of them don't respond to mouse clicks and the remaining one works fine. They are set up in the same way ie rowsource type is set to Alias and rowsource to the table name. I haven't changed any of the other settings. They all respond normally to keyboard control.

John,

You can use event tracking in teh debugger to find out what events are firing when you click the mouse on one of the illbehaed combos. This will certainly give you a clue to what is happening. The events I would track are MouseDown, MouseUp, and Click.
