Hey Martin-Scott.
Here is what I found. (I played the game, and it seems like sometimes it
doesn't allow user control after the space ship comes on screen). I am
programming a game aswell. Safe EArth - more like a supped up version of
SpaceInvaders. http://www.nextstepwebpages.com/games/saveEarth.swf
So I have been dealing with this stuff fresh. It looks like maybe, and this
would my guess, it looks like there is either a problem with the reloading
on the either of the ships (player or saucer). But more likely, and I
didn't spend too much time checking it out, but it seemed like maybe the hit
test on the saucer, triggered the lockup. That might explain why it happens
sometimes and not other times. Maybe you have some code being called after
that hit test and it wipes or somehow superseeds the controls code. Like I
said on my machine it was fine until the suacer appeared, than everything
else worked fine, just the ship controls were dead. So check those hit
tests, that's what I would do. Hope this helps, check out my SpaceInvaders
if you have the time, it is still being worked on.

Best of luck,

Paul V.
