I'm currently using a Dell Latitude D630, and have been having a mysterious problem right from the start: When I use the FN key + the down arrow to reduce the brightness of my screen, Windows Messenger (the stock messenger program that came with Windows) will start up. It is as if this is some special short-cut key for starting this application.
I tried removing Windows Messenger from the windows components, and now the key combination reverts to starting Windows Live Messenger!
Has anyone ran into this? I could not find any solution at all on the web. Of all my searches, I only found one lone post from 2005 on a form, of which that poast was still left unanswered.
