hmmm, i like firefox, especially with the GrApple Theme. never been a big safari fan. i think its the dark brushed metal skin - make my whole screen seem dark. I should try camino though to see what it's like.
back to my main point though, ive never seen anything like that before so its not like its a major annoyance, i also had Mail open too so that may have been guilty. I was hoping it wasnt a symptom of something nasty, or some sort of bizarre pop-up. Was wondering if perhaps if i was on a PC it might have done something bad to my machine....
