I, too, have had this problem after upgrading to 6.17.
Athlon 1800+ @ 1.53ghz, 512mb ram, Win XP Pro SP2, both fresh install with default settings and 6.16 .ini settings (copied 6.16's perform, remote, etc .ini's over to 6.17's directory).
Same "slowness" others describe when switching between windows or scrolling through buffer. With 6.16, I could hold down ctrl+tab and it would go through the windows almost instantly; with 6.17, though, there is a considerable amount of lag. I've also noticed when switching windows fast or scrolling through buffer, CPU usage spikes and remains at 100% until I stop. When the mIRC window is maximized and has either a channel or status windows up (with all of those channel or status windows 'minimized' in mIRC, this does not occur), dragging another window over the mIRC window causes 100% CPU usage as well.
Nevertheless, great program. Hope that was enough info!
[EDIT] I forgot to add, this is with my anti-virus disabled and with no virus/spyware on the system.
