I have a thinkpad t43p, and for some reason sometimes the left alt key will get "stuck". I'll press alt tab or something with the alt key, and afterwards any action I do will be the alt+keypressed action. So if I alt tabbed to trillian and back to firefox then click on a link, it tries to save the link. This only happens with the left alt key, and I have already checked sticky keys, it's off. I'm on a thinkpad t43p running windows xp pro. any help is appreciated.
