I did a little investigating and discovered the following: 
1) only the Warthog stick is affected. 
2) the issue only manifests when the stick is moved. Pitch or Aileron input. 
     ex: if I fire the trigger button it works as intended. IF I pull back on the stick and pull the trigger button, 4 things other switches are activated. 
3) When I unplug the control handle from the base all button functions active. This leads me to believe that the default circuit for a button is hot, and breaks in the circuit active the function. 
Conclusion: I think this is a hardware issue. Rotating the gimbal in the base of the warthog flight stick is breaking the connection to several (all?) button functions.  Not sure what would cause this. I dread opening it.
