Rogue and Druid

[Galahad]

I am having problems with my Rogue and Druid characters. When I go stealth with the Rogue and I go into combat and the stealth goes away the Interface tells me I have to be behind the target when I use my keyboard keys, but it works just fine with me using my mouse. A similar thing happens when I switch forms on my Druid, once I switch forms and go back to human form the Interface tells me that I can not use my action bar in that form using the keyboard, but agian it works when I use the mouse.

I am just wondering if there is a way to fix that problem, or if there is something that maybe I missed. Thank You.
