hi,
during watching the live replay, a pop-up will always show, and I keep on clicking the ok button, until I end the game (as an observer).

here are the details on faf lobby on feb. 19, 2012 (est):

22:28
snake57100:
Live Replay on bbf_bsd_08.v0001 : livereplay:GPGNET://faforever.com/snake57100.SCFAReplay

then, I reported it to the lobby and funkoff replied to post this on forum here.

is this something I must be concerned about? thanks!

note: I'm using the faf public beta client version patch 3611 (i think).
