Ok heres the problem:
The quickraidbuttons and click-to-cure are working on all my chracters except the zerker, which unfortunately is my main ^^
I guess there is a problem with the class detection:
when I try to cure myself with a potion via the button I get:
"spell or ability are no longer available" or something similar
and the quickbuttons in the grp window aren't defined either:
"parent.blub.... "
So I tried it on my monk and both, the cures and the quickbuttons do work.
I logged back on my zerker and still got the quickbuttons for the monk.
The Intercept and Assist Button still worked and also the click-to-cure buttons all did use the correct potion
So the UI didn't detect the berserker class properly and still acted as if I was still playing a monk.
Hopefully I can easily fix that, cause I need those buttons

thanks for response
