I'm looking for someone using one of those addons since I'm experiencing some bugs with them :
1) When I did chess in Karazhan, I couldn't use any spell of my action bar unless I mouseclick on it.
2) As I play as a holy priest, I encountered this bug also when I'm dead and into spirit of redemption form.
3) Bug also while in druid cat form. The cat action bar is ignored and when I press a key (1, 2, 3...), it triggers the spell of my normal stance action bar.
Are you also experiencing these bugs with some stances whatever the class you play ? Is there any fix ?
