When inside armoured vehicles as a gunner or commander, the turret will remain completely stabilised when enabling free-look.
(In a modded vehicle that has a completely unstabilised turret, i.e. Warrior IFV or BTR, enabling free-look or viewing the interior will magically fully stabilise the turret and cannon until you have resumed looking down the primary sight)
e.g. [[ http://www.armaholic.com/page.php?id=32922 | FV510 Warrior Mod ]], with turret config stabilisedInAxes =0, will act as if it had the value of '3' when free look is enabled, both inside the interior and in 3rd Person.
The new Nyx AWC's also have this problem. When using the GPS or with free-look disabled, the turret is non-stabilised; upon enabling free-look it magically becomes fully stabilised.
