If you like i could try to give you a working script.
The informations i need to do so are:
1. Folders to start WoW from
2. Resolutions and positions of the two windows
3. Do you want to have window-switching or pip (and when with what key)
4. what keys do you want to broadcast ? (A-Z, 0-9 F1...)
5. what key would you like to start the two wows
6. Do you need mousebroadcasting (and if with what key as a modifier to activate it)
