I've got pip switching all set up as described in the other thread, so I no longer have a true "main". Problem I'm running into when switching a lot of the main window will become restricted in fps, and one of the slave windows (previously the main) will be running at 100 fps even though it's supposed to be in the background. I seem to be able to fix it by clicking back and forth a few times, but in the meantime it slows things down especially in the heat of battle.

Thanks for any help.
