I've noticed the scroll bar for that list box is always screwed up, the scroll bar indicator always appears at the top, no matter where the list is scrolled to when you open the window. Try dragging the list bar up and down and try selecting again, that usually clears it for me.

A pig is a pal, who'll boost your morale, Though mountains may topple and tilt.
When they've blackballed, bamboozled, and burned you, When they've turned on you, Tory and Whig,
Though you may be thrown over by Tabby and Rover, You'll never go wrong with a pig, a pig,
You'll never go wrong with a pig!" -- Thomas Pynchon, "Gravity's Rainbow"
