I can't seem to get TX6 to work properly. Whenever I press and hold the bound button, I immediately get both the "press" and "release" audio cues and VoiceAttack instantly starts and stops listening.
My joystick is definitely configured to allow for pressing and holding the button, but just in case the button itself was faulty I tried binding buttons known to work with TX 1-4 and I still had the same issue with them.
Using the keyboard binding does work as expected.
