I haven't gotten that method to work yet. However, seeing that there seems to be some issues with it, I'm not going to worry about it.

Since I'm just running a priest as my slave and a mage as my main it doesn't really matter so much. I have 2 monitors and I just click over on the priests and cast off an offensive spell then click back to the mage while the other's casting. It's a bit annoying, but until there's a "fix" for the modifiers getting passed properly through the white list, I'll manage.

I was hoping to use all the keys on the numpad with modifiers for my G1-G18 keys. For now, I'll just have to settle with the base numpad and a few extras. I don't feel like Black Listing every key combination but the few I want to go through.
