I am still getting problems with the mouse click, only the buttons close to the middle is usable.

I have change my setting to in Maximize to
Main (400,0,1280x960)
Two (0,0,800x600)

I have Wow on 2 different directory right now, I have set the 1st one to 1280x960 and the second to 800x600
I have turn all the setting to low in wow. UI scaling is turn off

I launch the Instance from Octopus
Main on my left monitor(1)
Two on my right monitor(2)

As I get further from the middle, the mouse clicks are more and more off from my main
for example. I have all the action bar turn on in wow
In my main screen and clink and open the backpack, but on two, it will open the first back from the right
I put cooking on the first space and first aid in the right action bar
If i click on cooking in the main, first aid will open on my second.

I have try to toggle the WoW mode under the Client/mouse tab, with it on, it is a little more presice but not by much.
I just do not understand what I am doing wrong. ?(

The action bar buttons works fine if I bind it to a key on the keyboard, but I like to use the mouse click if it is all possible.

thks for any help or suggestions.
