Has anyone had a situation where key_up doesn't seem to behave
consistently? I am basically re-skinning the Frustum Hotel example
and it's been behaving just as I'd hoped except that trying it on my
secondary machine (I'm away from my development box) has the key_down
stuck or the key_up not being triggered. So, when moving forward with
a peck of the up arrow, it goes and goes. Probably something I did
when cleaning up my code because it was perfect but, I can't see
anything obvious and I'm wondering if it may have been an issue for
someone else. Thanks
