Hello. New to KSP and Mods. I have version .24. I've installed MechJeb, Kerbal Engineer Redux v0.6 and Enhanced NavBall v1.3. In all cases there are no buttons on screen to select, modify or otherwise interact with these options. The vehicle modules for MechJeb and KER are available and I've attached them to the vessels. For MehcJeb and KER I've dropped the folders into the Gamedata folder. Enhanced NavBall is in the KSP_win folder. I've searched the forums but can't figure this out. Thanks Ryan
