Binding Spells to Keys?

[Malgor]

I am not using any FTL modifiers as far as I know. I am not using shift, alt or ctrl.

Right now I am experiencing just two problems.

1. In WoW I bound my target keys 0-4 on the number pad with 0 being self, 1 being party member 1, and so on. I unbound any keys on my other characters that were associated with the number pad, so only my healer would be the only one with those keys bound. PROBLEM: Only on my druid's screen can I use those keys to select who I want my druid to heal by pressing 0-4 on the number pad.

2. In ISBoxer I created four heal buttons on the number pad, each associated with a different heal spell. I can activate 3 of the four, but for some reason when I press the button for /cast Rejuvenation, the spell won't cast no matter what button I put it on.
