Alright. Thanks.

I can see the compulsory ID number being a bit obnoxious... in my mind it should only appear when a conflict does happen.

If I'm not mistaken, the "Lock logs" option still behaves in this manner. If you open up two mIRC instances, each instance's logs are locked (write access denied) from the other instance, forcing a ".1" digit to be placed at the end of the second mIRC's log files.

Well. At least I won lunch.
Good philosophy, see good in bad, I like!
