NUI and auto dismount in flight.
 

I disabled all addons but NUI but I still cant seem to enable dismount in flight. The box checks but gets unchecked when I go back in. If I disable NUI it seems to be ok. Any ideas?

None whatsoever as nUI does not twiddle with any of those settings in any way. Very odd indeed.

I dont know myself since i use smartmount, All this does is lets you set 3 sets of mounts on 3 diffent keys,

Mine are Shift 7 8 and 9.
S7 = random fastest mount
S8 = Random ANY mount
S9 = Vendor mount

So you can always try this, jsut dont forget to change the setting in /smartmount to always dismount even in the air.

Hopes tihs helps
