Or just one coconut of a mouse configurer.
I figured out my Action Bar problem.
Based upon my recent whim that my mouse button to keyboard mappings were the cause, I tried a very simple test.
I hit shift+control+4 on the keyboard, on the assumption that the shift+control were being enabled by one of my extra mouse buttons (since I had mapped the button to shift+control+[), and I think I noticed the problem when toggling that button to talk, while hitting 4 to fire an Arcane Shot.
So I test it out and....zippo. One of my right action bars swaps into the position of the main action bar that's default mapped to your 1 thru = keys.
How bout control+shift+1????
Yepperz. Action Bars are back to normal. Testing a variety of numbers, I learned that holding shift and control, you can swap your action bars around on the fly by with the number keys.
More testing revealed that keys like [ ] ; ' , . with no modifiers seem to take no action in the default WoW setup. I remapped all my alternate mouse buttons on my new mouse to those keys and I'm back in business.
