As far as why there's not a checkbox, there never was before altho we never had multiserve before 6.0 so it wasnt needed altho it would make sence for a new feature. I'd agree with it.
As for why it wont keep, I havent a clue. The only thing I could think of is a screwed mirc.ini file, but that shouldnt be your first line of thinking for every issue. What version of mirc do you have? Is it only with this version that it's happeneing - meaning have you used other mircs and has this issue happened before?
