I have had this problem for the last couple of years.  I cant zoom in or out while in a plane, that includes buffs too.  when I press z on my keyboard it just limits me to one setting, and I am unable to adjust using the []  keys.  I should say that i dont have this problem while in any gv's and I am able to adjust zoom function as needed.  does anybody else have this problem? I have a gateway 820 pentium 4 computer with 2 processors and use the x52 joystick, but i also had the same problem when I was using a logitec joystick.  I have the x52 mapped to zoom in while in the game and it only works with gvs.  I have tried remaping the zoom in key to something else but it dont work either.
