Do you play with both screens going at the same time or just one? To give you an example I've got 2 large screens and I play Poker on the one on the right. The HEM notes windows are the same size but the HH windows are long or short. So I have the HM notes opening in the top right corner of the left screen and the HEM histories opening directly underneath those. Then the lobby in the bottom left corner of the left screen. If I used one screen I'd probably open the HH's at the top left corner and the HM notes in the bottom left.
You need the Autohotkey Window Spy- just open any autohotkey, right click the icon in the tray and you will see it there- look at mouse position, on screen and you will see the numbers change as you move your cursor. Just put your cursor at the co-ordinates you want the window and jot the co-ords down- type them into EZCash and the windows will move there when you open them up. You can leave the HH's open and they just pile up on top of each other- the newest is on top.
I wouldn't mind another person to test, if you are playing on Party today and you want to then drop me a PM.
