Please dont consider your post a rant. The more info we are given, the better able we are to help you.
That said, the only things that came to mind are really longshots
-my first thought was what font are you using, even tho i cant see why that would cause your off and on prob. Still, it wouldnt hurt to change fonts just to see if it made any diff
-scripts. i know you said you dont use any, and that you reinstalled mIRC, but have you double checked in remotes/alias/popups just to be sure what is there?
-i dont use 2k, so i havent any idea what options are there, and by "settings" i'm not sure if you meant you checked mIRC's or windows as well
-i'm not familiar with any trojans that do that, but running a couple good virus scans never hurts and is usually worth a try
Sorry i cant be more help. Could have sworn we had someone post about the same problem a good while back, but i couldnt find it and my memory banks arent reliable. I'll run a few more searches and let you know if i find anything. Hopefully someone else will be able to help better than i can.
