Hmm, i've done a fair bit of bugtesting, but it's kind of hard because we all have our clients set up differently. Shouldn't make much of a problem though.
Could you copypaste the ini file it made here? If you can't find it, it's in the mirc settings folder. Like... Documents and settings/application data/mirc/.
Also, I haven't coded in a password for the channel... I'll add that tomorrow after uni =) Kinda tired and working on something else now, should probably get some sleep T__T
EDIT: Actually. Probably best if you didn't. Send it via personal message with server and password fields removed :)
