It's worth noting that having auto accept on is quite bad practice...some IRC viruses are set to auto-send virus files when you join a channel, some even on a timed delay. You could (and it's not improbable) accept and even run a virus on your system. If you are having this feature enabled, for sake of all of us (as infected clients do affect us all) run a 1/2/3 good virus scanners on your system weekly/fortnightly and preferably scan every file you download. See this post
for some good safety suggestions and resources for keeping your computer safe.
Also worth noting (yes, every time) that mIRC is not a mass file sharing program, it's a chat program and downloading (IF you are) mp3s/movies/software etc. is illegal and as aforementioned, often leads to you being infected.
However, if yer not downloading such files and what you download in this 'queue' is perfectly legal, good on you and I hope you have fun on IRC
