when you say it does work.. what exactly do you mean? do your wows not pop up? do they not maximize? or do they maximize but don't jump when you hit the pip key?

it looks like you assigned F6, F7, F8, F9, and F10 to regions 'region0' thru 'region4'

if you click on region0, and hit F7... region1 should swap with region0... hitting F6 at that point will bring region0 back

is this not happening?

(btw, you should UNCHECK auto-add-windows-titled... its not needed when you use commands)
