@Teen: hm. maybe mirc overwrite this ini-key when exit. just check [about] and [user] section in your $mircini if you install mirc in portable mode, or HKEY_LOCAL_MACHINE\SOFTWARE\mIRC\LastRun in registry editor (Start -> Run -> regedit).
@napa182: I do not understand your anger. forgive me, if something wrong.
@blackvenomm666: this snippet just example for reset trial, not serious for works.
