Fade changes 1.2.0 bug…?

Hi,
I can't get my Fade Changes to toggle to work with 1.2.0?
I program it to the top left trackball button (Kensington Expert)
but it don't toggle… I have tried different options and cannot get the "mouse" to toggle it…
The manual Fade Changes touch button on the screen (RH4) works fine…

Anyone experiencing a similar issue with 1.2.0?
