This seems to be a simple problem, but I can't figure it out. Any help would be greatly appreciated.

I need a few CComboBox controls on a form. I can add them just fine, change their properties and add entries to them from the form, but when I am actually running the application, the combo box will not drop down.. It acts as though it's dropping down, but the height of the list is 1 or so. All I see is a black line below the control. I can set focus to the control and scroll through the items using the arrow keys, but the dropdown doesn't work.

I've had the same problem on 2 different computers. I'm running VC++ 6.0 on Win98 and the same on Win95. Thanks in advance!
