I used to be able to push and hold the scroll wheel on my mouse and the Chase Plane Interface/settings would open, allowing for instant adjustment and settings changes, this no longer happens and I now have to open CP outside of  the Prepar3D environment. Have my settings been corrupted, if not, will this feature return to CP. It sure makes using CP easier with it.

I also have this issue.  Is there any way to set it?  I thought it was a fantastic idea and made updating the camera settings simple and fast.

Just figured it out.  You have to enable it:

PREFERENCES
CAMERA TAB
MOUSE CONTROLS - Enable "MB VIEW SELECTOR (HOLD STEADY)

Thanks, I saw that but couldn't figure it out, so left it alone, wish Oldprop would release a detailed manual.
