I start to notice that when mirc is downloading the file and at the time same, I'm copying files (ie. about 2GB+ of files) to another computer in LAN. There is drastic drop on the download speed within mIRC. I don't believe I have issue with mIRC 6.x. I know if there multiple downloads occurring on mIRC. mIRC will give priority to one offer better speed. Unless this is new feature in Window 7 that basically force priority on the pocket that is nearest?
