Not woking with the aaddon WorkAny, I had no error in BugSack, so I started disabling all addons and enabling one by one. I arrived to these conclussions:
1.- With all addons dissabled, it still was not working. It happened that I had one key assigned in "Interface options" > "Self Cast Key". I changed to "None" and then it worked in all bars. I beleive that by default WoW comes with one key assigned.
2.- When I enabled, "MoveAny". Stopped working partially:
2.1.- It still works with what MoveAny calls Actionbars 1 + 5 +6. But,
2.2.- It does not work with the rest of the bars: bars nº 3 (right bar), nº 4 (left bar), 7, 8, 9.
I will search for help in WorkAny too.
Cheers.-
