Camera issues

When i use my scrollwheel in mw3d it doens 't zoom in at all.

I tought it may have been because of some library not working together with my mouse / mouse drivers.
But i made myself a small application to test this (in the same way the code is used in mw3d) and i did get output.

I'm running xp

java version "1.6.0_15"
Java(TM) SE Runtime Environment (build 1.6.0_15-b03)
Java HotSpot(TM) Client VM (build 14.1-b02, mixed mode, sharing)

(i also tried editing the code of the mw3d camera so it would just respond on other keypresses but its a pain to compile it for some reason.The version i had in mind responded to both mouse-down and middle mouse click, not the most functional but anything beets moving in that scene with wasd)

I also tried to use another mouse, just in case...
this mouse also generated output in my test project but failed to comply in mw3d
(both were logitecs if it helps)

any suggestions on how to fix this issue?
