I believe there have been reports of games conflicting with mIRC and causing problems with the DCC function. Try doing a
Search. Are you sure it's only when you're running the game? Maybe Norton is interfering with it?
Either way, if you're using mIRC to chat and not to download illegal files, it shouldn't cause you many problems
- After all, if you're downloading a file from your friend, the most it's going to take (provided it's not an illegal movie or music file) is 4/5 minutes. The game could wait!
Happy chatting!
