Inability to use FTL Assist

[Alge]

No, I thought the whole point of FTL was that they would automatically assist whatever guy was the focus.

The F in FTL stands for "focusless". The FTL system as implemented in ISBoxer will assist whichever character is active.

Anyway, I think the fix for you is simple:
1. In your FTL Assist Me Mapped Key, under Advanced in the bottom left pane, change "World of Warcraft: Use FTL Modifiers" from "Off" to "On".
2. Then, you'll also need to change the Key Combination from Ctrl+Shift+Alt+G to something without modifers. Backspace is a good candidate, or an unused F key (but not F4).

This will result in the following macro being generated:
/assist [nomod]player;[nomod:alt,mod:lshift,nomod:ctrl]Stormshade;[nomod:alt,mod:rshift,nomod:ctrl]Sacredfury;[nomod:alt,nomod:shift,mod:lctrl]Bladewraith;[mod:lalt,nomod:shift,nomod:ctrl]Shadowrune;[nomod:alt,mod:lshift,mod:lctrl]Frostphantom

That should fix it. Make sure the ISBoxer addon is being loaded for all your characters.

Let me know what fails to happen if that doesn't work.
