^ Using the Pause has been become a habit now after seeing a bazillion windows pop up in my alt windows when I don't. Also, the /assist /lightening bolt , "why am I only see 1 lightening bolt?" "oh, I'm typing text in my alt chat boxes, nice".

So yea, make it a habit to use the Pause button and the Do Not Pass list. I've only been multi-box'n for a few days now and you get the hang of it fairly quickly. I only game a couple of hours a night.
