so when my computer boots up, and i click something on my desktop (not the bottom bar of windows), windows explorer keeps popping up with an empty search window.
same with firefox 5.0. i can't actually visit any pages before i've entered something in that damn search bar, because it keeps moving my focus to the search window.
i have windows 7 home premium, firefox 5.0 with adblock plus 1.3.9, noscript 2.1.1.2, norton toolbar 2011.7.0.8. i don't think it's a virus, because this problem also happened the first time i booted him. back then, i thought it was a problem with my mouse, but i'm not so sure anymore.
any ideas?
edit: search indicates that it's partly due to my usb mouse, but that sounds strange.
