Strange overlay keyboard - Constellation Alpha

[Robsterios]

Hi.. when depressing the scroll wheel button on my Constellation Alpha Joystick, a strange overlay keyboard comes up on the screen. It can't be moved or closed. I simply have to close down DCS and doesn't even show in task manager. Simply have to reboot the computer to remove. Any ideas on how to remove this function.. It's fairly annoying.

Check if you have something Windows bound to that button.  That looks like a Windows touch keyboard getting pulled up for some reason.

I've disabled the Windows touch keyboard which is not it. Virpil configuration tool only has these buttons as single buttons 21/22 ... I'm at a loss..!!
