So I'm a moron and forgot to attach the source files. ;) Sorry about that.
Here's a repost.
> I'm having a problem with headtracking in java3d. Something

> else I'm missing) is not being updated regularly and so the
> viewing frustum doesn't change as I move my head around.

> I can force the update by moving my mouse in and out of the
> window border or by moving another window over the java3d frame.
> Overloading the head tracker's input device's
> pollAndProcessInput() method indicates that this method is being
> called regularly. However, polling the View's userHeadToVworld
> transform every 30ms indicates that this transform is *not* being

> window manager. So although there's a thread asking the
