I was trying to create a ghost image with insert and lines from azel 270 -13 when I received an error. If I use an mged hotkey (ie r for right view) to change the view of the vehicle, I can not then use the azimuth or elevation tabs under the View pull down menu. If i try to do this I receive an error saying 'expected floating-point number but got ""'. The log file if needed can be provided.

Rob, we were unable to reproduce the floating point error message in testing using the steps you mentioned. Tried various combinations too. There is a minor issue where the display and the sliders can get out of sync, but that's merely annoying and doesn't affect it's functionality. Thanks for the report regardless!
