here's what's happening.. . . i'll be minding my own business, doing regular computers tasks like chatting or surfing or typing or just watching a video. all of a sudden a small window, maybe the size of the "you are not connected to the internet" window, flashes on the screen. the first time it appeared was when i was typing, so i thought maybe me hitting the spacebar was what made it disappear so quickly. but then it has happened a few times since then, and i've just caught it flicker out of the corner of my eye. i have no idea what it is. it doesn't animate like most os x lion windows do when opened, it's literally a small flash, too quick for me to see what it is. i've restarted, i've looked through my activity monitor (though not extremely thoroughly), turned on my firewall, and it still just happened a few minutes ago. it's obviously not a big inconvenience, but it's kind of weirding me out just because i can't ever get to see what the damn window is. if anyone has any suggestions on what i can do to figure this out, i would be most appreciative. thank you so much!
