you can use on me:*:<EVENT> to trigger events ONLY when you trigger them. I also silenced the timer command by prefixing it with a dot. Seeing those Timer started & Timer halted will get quite annoying i also used ^* as the level, the ^ makes it do whatever commands you put before the commands mIRC does internally.
