After I make the change to the csweapon.xml, what do I need to do to see the change ? In other words, can I make the edit, save it, and just reload the plane, or do I need to choose another plane first, then reload the one I am tweaking ?

I have the X52 FCS and separate rudder pedals. When I go to "Controls" in FSX it also shows two entries for some sort of mouse control before the FCS and pedals. I have tried setting the controller from 0-5 in csweapon.xml and cannot get the fire button to work. That's why I am asking what process to use to see the changes after the edit.

I also noted that the "button" entry is one off from the actual hardware button so I tried assigning the button as "0" for the fire button press half way and "14" for fire button fully dpressed. No joy.
