Are you playing farmvill while workin in flash and farmville is causing flash to cash on you?
I've never played farmville, but I don't think it's in flash from what I can tell, I could be wrong, so if your question is why is Farmville crashing then I'm not sure, probably something on the host's end, happens a lot with these Facebook games.
I am only playing Farmville not working on flash thanks a lot for getting
back to me have a good day !! Lise
