I like the original ISBoxer setup on 1 monitor, with the small region windows on the bottom that could be swapped with a mouse click. But the videofx overlay for my healer was blurry, so I went with the full screen stacked style + dxNothing. I put the feeds on a 2nd monitor.
How do you switch toons with this setup? Can't swap windows by clicking on them anymore, which is what I'd prefer. Do you setup a hotkey? I'm thinking there has to be a better way than alt tab.
