I recently installed windows XP Pro and found a problem when using mirc. Basically the combination of XP and mirc causes excessive system lagg when switching between channels which have background images apx larger than 400K, notable effects include lagg within mirc, sound output (ie winamp) and a "sticky" mouse.

FIX: the quick fix thus is to not use images larger than apx 400K. Use jpeg (jpg) images as the file sizes are considerably smaller than bitmap (bmp)

This "bug" occured in both mirc versions 5.91 and 6.03 when running windows XP Pro on a 800mhz duron with 576mb ram.
