Not sure what's going on.  It worked before.  I did a fresh install a few months ago, but left the brakes assigned to a button on my yoke.  Today, I wanted to set up the toe brakes and it won't let me reverse the axis.

 

I click on the check box and the red check mark shows up.  As soon as I click anywhere else, it goes away.  If I reverse the right toe brake, the check mark shows up, then when I click the box to reverse the left toe brake, the check mark on the right toe disappears.  Weird.

 

Any help greatly appreciated.

It may be that your yoke has button that is permanently sending a signal that it is pressed. Saitek yokes have the three position dial on the right horn, that can do this. Try continually moving the brake axis while you make your assignment/tick the reverse box and press ok.

I'll give it a try.  Thanks, Peter.

Aargh!  No good.  This is driving me nuts.  I've already deleted a few extra axis that was assigned to it by default, so right now, I only have the rudder axis selected.

 

It worked fine on my last install and I didn't do anything different on this one.  It's also working fine for FSX.
