I'm not sure if this is a bug or not but mIRC practically freezes on a single nick change after it's been running for half a day or so.. I don't think/know if this is related to that GDI bug, just a problem I've had for a while, mIRC just gets really laggy to switch between windows as the time it's running increases and if I get a few new queries at once (like 3-10 privmsgs for example) they all lag mIRC horribly as each window appears one by one.
