After running mirc continuously for about a week, the entire WIndows XP system lags to hell. Basically, user interface of all program will now use 100% cpu. Mirc's own options dialog box will take 1 minute to open, task manager show 100% kernal cpu usage during that time.
Same thing with other programs, flashfxp's option dialog takes minutes to open 100% cpu used by flashfxp.
After shutting down MIRC, problem dissapears.
This problem appeared around early this year, So I'm guessing around Mirc 6.0 and after. Earlier version doesn't have this bug.
I've used Windows XP SP1 and SP2, P3 1GHZ. 1gig of ram.
And if it helps, 3 hd, 1 dvd-r. ati 8500 128meg.
Someone with a p4 2.4gig is also effected.
