I will check if it occurs on public servers. Never had any problems with .60. Yes whenever I'm in the vicinity of another player i lose my voip option and i desync. The desync eventually goes away but for a good five minutes i am unable to do anything

It started about two months ago

From what i know it occurs on only stable. I have not try public but it happens on multiple private servers. And 32 and 64 bit clients both result in this problem happening again
