Win7 ultimate RC 64bit & APT 1.1.0 beta6 64bit:

under 3d editor: Panorama View you can set values:
"set as zoom max (+ sign)"  and "set as zoom min (- sign)"

lets set the values to:
"set as zoom max (+ sign)"  = FOV 40
"set as zoom min (- sign)" = FOV 100

but under
Panorama Properties -> View properties:
it then gets displayed:
FOV limits: Min 40,00 Max 100,00

so you set a max value first and the min value will be affected and vice versa...
... at least the labeling of FOV value of max and min is mixed under Panoram Properties-> View parameters->FOV limits.
... or why not renaming the label "FOV limits" to "zoom limits (FOV)"
