setup regions for all three accounts (region1 = account 1, region2 = account2, region3=account3) you can then setup maximizer window dimensions that are tied to those regions. All keys are passed be default, you can modify that using a whitelist/blacklist configuraion in the do-not-pass area.

Dual core - set affinity of main account to 1, second account to 2 (you mentioned that you have three accounts but are only describing two in your setup, which confuses me)

I have the same problem I guess. I have one computer and have 3 accounts. So far I can load up the two accounts I want after realising that I needed to set region to region2 being in the UK. I'm confused as to the cpu selection though. I have and amd dual processor 3.2ghz, with 4gb ram and two monitors. I want the main leader to be on monitor 1 and the follow guy (second account) on monitor two, I think I might be able to figure that one out I'll let you know. I have followed the macro selection to get the guys to kill the same target by putting this macro on the second account
/follow focus
/assist focus
/startattack [target=focus]
the key settings was set in the setup part, I tend to use the up, down ,left,right arrow keys ... do I do that for one account or will it move both? IS there anything else I need to do?
Your help is very much in demand here as I'm trying to level 2 sahmans at once. Thank you again
