My stupid mouse is being a smart-ass, trying to tell me I've been on LJ too long (maybe four hours straight). It's closed my browser for me twice now, most recently while I was scrolling and accidentally passed over the upper right corner.
On second thought, the first one wasn't the mouse's fault. I tried watching a video solarbird recommended and it crashed Firefox. But it's still a crappy mouse, and hopefully it'll get replaced later this afternoon (after a nap for me).
