Yeah it seems to be just SEA. Discoes happen I know, but last night was a right hard freeze which makes me think hardware. One thing I should check is power management, cos with tods there are long periods with not much happening. Still, Power Management shouldnt kick in when theres RW traffic and text messages going on. Iceydee mentioned a hacker trick which can freeze PC's, but i don't know about that.
All I know is I never get problems in MA or other arenas.
