No Mousecontrol after activating Mouse Cursor

After activating mousecursor in 3rd Person template,


my Controls wont work anymore (rightklick and leftklick for several funktions for controlling the character).

It seems, i have to leftklick for mouseactions. So if i hold the left button, it accepts my function to use the rightbutton.

So others dont work anymore. i have one for only left button, one for only right button and one for both mousebuttons. Well, the other mousebuttons, too, but there just working, while pressing left button.

How can i deactivate the neccessary to klick left button for actions?

I am the only person, where want to make a Mouse driven Game?
