So I got the SVN version for WOTLK, but it won't let me change pages on the action bars. Example, if I hit shift-2 in the normal unenhanced WoW interface, the bar goes from bar #1, to like bar #3 (whatever the action bar is on the far right side using default interface)
If I do it in Bar4, nothing happens at all. Basically, what the dude one page back said was happening with him.
Bar switching now works for me with the latest PTR build. Since I didn't change anything except applying the new PTR patch, I guess it was a problem with the PTR itself. Though the config is kinda broken now, but this happened to other addons too.
