Regardless of the profile that I use with my X55, when I press either Switch 3 or Switch 5, it causes the under carriage to activate (it's effectively the same as pressing 'G' at the same time). I've even used the default profile, which does not have anything assigned to either switches 3 or 5, but it still has the effect, i.e the undercarriage is activated!
It is only a problem with P3D as FSX is fine. I first noticed the problem with the AS A320X, but it is also the same with the default Beech Baron. I've got all the up to date Saitek drivers and software loaded.
Does anybody have any suggestions or it is just another P3DV3 bug?
