Hello there!Wierd behavior occuring off two buttons on the Throttle Quadrant of my Hotas Warthog. The 'RED' button on the throttle handle will release (but not set) the parking brake (?). I want it to reset the altimeter when I'm using REX real time weather. I went into FSUIPC and programmed the button to send the keystroke which I set up in FSX for altimeter reset (( ; )) it works ok and does reset the altimeter if REX Weather is operating. It ALSO kicks the parking brake OFF (if it's set) but doesn't cause it to come back on if I press the button again.From this I deduce:The button may be sending a braking command, which also turns off the parking brake.Darned if I can find out why this is happening. I use LINDA as well, I have NOTHING set in LINDA for the Red button. I use linda to fly my PMDG 737NGX.Spent a LOT of time on this with no joy.I did have TARGET software on the system, removed it (should I be worried there may be detritus from Target causing a problem?) Also temporarily tried out the G13 keypad but was not able to get it to work with FSX at all, so never programmed any buttons for it. I very well MIGHT have programmed the red button on the throttle handle to activate the parking brake in FSX - any help on this would be greatly appreciated, thanks in advance.
