When using the -i switch, mIRC 7.78 does not correctly read settings from the indicated mirc.ini file.
Checked [dirs]/getdir, [logging]/status=off.
Regarding [dirs]. When using the command $mididir, $mp3dir, $wavedir, the corresponding directory is called, while in the mIRC settings it shows a completely different one.
Don't know if there isn't more to it. In mIRC version 6.35 it reads correctly.
Regards.
