hey, i'm kind of a mac noob and i am having a problem with safari...i have my homepage set as facebook, and every time i open safari or maximize it from the dock, i get a flicker

the problem seems to only be happening when i open facebook (that i have noticed). anyone else have this problem? any possible solutions? could it be a virus?

i'll hang up and listen

can someone please open facebook and see if they get a flicker?...
