Forums mIRC Help High cpu usage when scrolling/marking text

Maybe it's cos you have 1 CPU core? i have dual core, windows xp 64 bits have better support for dual core and more ram, i using windows xp 64 cos i want to use all of my ram, and as i said before i have no problem, i running 3 mirc right now, and i also played a game, and i haven't noticed any problem at all with windows 64 and mirc, how much ram do you have? something make your computer run 100% CPU, and i don't think mirc alone can create this problem for you, must be something else too.
