Account glitch? My screen flashes black when I click on ALL viewers

[JungleMoon]

so basically, when I log on I lag, then when I go to click (maybe chat or something) it starts blinking black, it has been doing this for several weeks now and I'm getting very frustrated. I re-installed it-didn't work. I have no clue how to update firestorm, so maybe thats it? I just want to play SL Normally! Any help would be very very appreciated! 

 

*Photo below is what it does when I log in and click in game:

if it's possible try log in on a different machine, if it's not happening there i'm affraid it's your machine and not sl related.
