Oh right... I somehow forgot that pulldown menus can be used as their name implies, by clicking and holding down the mouse to open the menu, and release to make your selection; I've gotten so used to clicking to open, having them stay open, and then clicking again to make my selection (at least since Apple first enabled that feature in System 7). All of a sudden, I'm much less proud of my home-rolled pulldown-menu implementation I've been using.
