I, being the lazy person I am, have a bind so that I press a button to turn off and on turbo. For some reason, after all my energy is used up (only while using the bind), I can't boost again unless I click the normal boost button twice. Not a big bug, but (damn you alliteration!) it's annoying.

It's not a bug.
The turbo needs to be let up before activating again.
Maybe you can put a -turbo or whatever at the beginning of your bind? I dunno what your bind setup looks like exactly.

just change your bind so that it turns turbo off b4 it turns it on every time.

if you cycle through the views using F2 when you get back to the cockpit view the turbo will kick back in again.....
