I have (as far as I know) a unique setup for this. What I did was setup a "reset region" on the 2nd PC that was full-size. I setup 4 normal regions for regular play. Then I have a separate keymap for "Alt Window Functions" where I have CTRL+ALT+NUMPAD1 set to send the current window to the reset region, and CTRL+ALT+NUMPAD0 set to reset all regions back to their home region. It works like a champ. Remind me later (PM me if I forget) and I'll post my config and more details when I get home tonight.

Note that my setup isn't the easiest thing to use in the heat of battle but it's great for use at mailboxes, vendors, etc. when you really want to see all the item/text details.
