HELP: Toggle Windows

Hi fellow boxers, I've used ISBoxer for a few months last year and didn't require help and just returned to a dual-boxing setup but for some reason I can't just figure out why my Windows toggle (I've also tried next/previous Window and assigning hotkeys to my Windows) doesn't work. I can switch to my second/next window but can't switch back to my other/previous window. I am able to switch back if I press the "alt" key (or if I use alt-tab) first then my hotkey. I am using sweet FX and windowed fullscreen if it helps. Thanks in advance.

It may help to see your profile, and if you could tell us exactly what key (or combination of keys) you're pressing to switch between game clients.

Thanks MiRai, I am using hotkeys F1 and F2 and I've freed my default WoW keybinding of those keys (both clients). Also, I have multiple displays but I configured ISBoxer to use just one display with no swapping (so resolution for Video FX are consistent). A link to my config is below. Thanks again.

P.S.
I used ISBoxer before (last year) with more than 5 accounts/clients and didn't have this issue before, I might just missed something.

I see nothing out of the ordinary in your profile, so you can try...

1) Removing the option to make the keys global to see if that changes anything

2) Repeatedly cycling between the two keys a few times to see if the game clients eventually begin to swap

3) Using a different set of keys to see if the problem persists

I've found what's causing it ... Overwolf! Thanks MiRai, I just want to let you know I've learned a lot from your videos, they are mostly the ones I'm using.
