Is the mouse scroll wheel meant to work in the IPTC Info window to allow a quick scroll down the list of items to reach those that are initially hidden? I'm on Win XP SP2 and it doesn't work for me, unless I've missed an option.
It is supposed to work, but Windows has this funny way of sending mouse wheel events to the focused window, even if it doesn't have scroll bars active. I made it so you can click in any background area and drag the mouse up and down and it will directly scroll.
