Forums Bug Reports AMD64 And Mirc

Guys,

If Mirc is started all goes OK ..but within 2 or 3 seconds it takes 99% of CPU Usage.

I tried all sorts of things to get it working. I even tried compatibility mode on every setting.

I'm running:
Windows XP Pro (32-bit)
AMD64 3200+
1GB Memory

Any fixes for this?
(WIndows XP 64 bit edition is NO option)

I've experienced the same problem u seem to have with my AMD64 3000+ on Windows 2000 Professional, i didn't however experience on windows XP Pro 32bit, and of course XP 64bit has its own problems.. but if anyone knows how to resolve the mirc cpu usage problem help pls :]
