In a dialog, when I have a command like:
/load -rs blah.mrc
and blah.mrc contains on LOAD or on START commands, mIRC will auto load them, not even asking whether I want to initialise them. I enable that option to ask, and even when i try from doing it from an alias instead of /load -rs, it doesn't work too.
If I'm not executing it from a dialog, even aliases will work fine, as well as the manual way too.
