This dialog allows you turn on/off your groups ( #group ) as you need via the dialog. If you turn one off a second dialog appears allowing you turn off the variables/timers associated with the #group as you need.

By default it is set to open in the top right hand corner of mIRC ( if mIRC is fullscreen ).

Update 15Sep08: Fixed it to unset timers that are numbers and not text.
