Can't Change Internal Views

[planenut 19]

This is intermittent problem I am having.  After I have set up my views using the Ctrl - keypad they work fine (usually).  After doing some flying and exiting XPlane (11) and then starting the sim again I have no internal view control.  I only have the default 3D forward view.  Can't move around using the mouse or using the keypad.  I can manipulate the external views just fine with the keyboard or mouse.  I deleted the Output Preferences once and let XPlane rebuild.  It worked ok a few times but then reverted to the same old problem.  If I had any hair left I would be pulling it out.  Sure could use some advice.  Thanks.

Wouldn't you know.  As soon as I posted my problem, I found the cause.  In the Settings Window, in the Graphics tab at the very bottom, I had checked the "Enable TrackIR &TrackHat view tracking in 3D cockpit"  Once I unchecked that box everything works as designed.  Can anyone spell "pilot error".
