I was able to succesfully play the sareware version of DOOM for over a month,
but then I got the registered version, and now my shareware version has this
strange bug. The reason I kept the shareware version is that I heard about
that disk-laoding-jerky-slowdown-bug and I wanted to be able to copy my
shareware .exe to fix this problem. Anyway, I got the slow-down-bug on level
3-6 (I think) so I copyed the .exe form the shareware and when I ran it
my character started running forward and I could't stop him. Evrything else
seemed fine. I then reinstallled the shareware version from the .zip file 
and I had the same problem. I no idea why this is happening, it used to
work fine and I have no problems with the registered version. 

The only thing that I did was I was playing around with the controler type
to see what would happen. When I switched to joystick-keyboard mode the
game went crazy (i.e. they guy was running on his own) but I fixed that by
centering my joystick with those little dials that ost joysticks have. 
That's the only thing that is different now, except that I now have the
registered version (in a different directory). I've tried everything. I
even reinstalled to make sure I hadn't inavertantly messed something up, but
it's still messed up. 

Anyone have any ideas about this. I guess it might be a joystick problem,
but I have the game configured to no joystick and I even unplugged my
joystick and disabled the joystick port. Any help would be appreciated.

Thanks,
