[WoW] Middle mouse Button problem!

[lax]

I am going to guess that this will help you:
FAQ: I am using a mouse button as a hotkey for something, and sometimes it doesn't work, what am I doing wrong?

Sounds a little similar to a Problem i had at the beginning.
Using a Razer Naga, the Standardbindings sended wrong Inputs to Wow.
Example: If i pressed 4 on the Naga, the Main did Actiobutton 4, but the Toon switched the Actionbars, becaus for the Toons there was sended Shift+4.
After cofiguring new it work....a little Time.

After changing the Keybinds in the Naga ich changed it in WoW to.
What happened?
I logged in all Chars seperately.
Main...Keybind changed to 1-12....worked.
Toon1...worked.
Toon 3...worked.
Toon 4....worked.

Logging in all together......the same Problem again.
I had to bind the Keys new with all Chars logged in to make it work.
I don´t know how, but then it worked.

Maybe you should check the Keybindings on a Toon when this in a BG happens (right after it happened).
