I have no idea what the problem is--I'd guess memory/display limitations.

But I've always had better luck when I used controls from the Forms toolbar.
The dropdown doesn't behave exactly like the combobox, but maybe it'll be
sufficient for you.

I've placed a combo box control on a worksheet for month selection. Most of
the time, everything is fine, but every once in a while the control is
replaced by a blank box with an "X" in it. When I click on it, I get a HUGE
form of my combo box, too larger to fit on the screen. Rebooting does not
help.

HELP!
