why does mirc 6.12 seem to lag every 30 seconds or so when in channels with more than 500 users. the problem is amplifed as you join more channels with more than 500 users. all scripting is removed and the window buffer is set to 2500. i'm using winxp pro on duron 1.3ghz, asus a7v, 768mb ram, 40gig HD. i have ignore on *!*@*.* and exempt a limited few users, so i only see their traffic. joins/parts/quits/modes/nicks are all set to off in events handling.
