First of all, thanks to those who helped out with my vblank server.  Moving
right along to my next exciting adventure...

Here's the short form:  my program needs to have raw keyboard input.  Since
I have my own Intuition screen, I thought that RAWKEY messages would solve
my problem.  What happens now is that when I hold a key down, after about
one second my program locks.  When I release the key, everything resumes.
Needless to say, this behavior is undesireable.  Is there a trick to using
RAWKEYs, or should I be using a different method for raw keyboard input?

Additional background:  My program is animating at 30 frames a second.  Each
time through the loop, I empty out my IDCMP port.  All very straightforward.
I've had the same results with and without Dmouse running.  What I don't
understand is that RAWKEYs should only be generating key up/down messages,
so holding down a key should have no effect on anything.  Unless the
keyboard.device or input.device are processing key repeats and somehow bringing
the whole works to a grinding halt.  I still don't see how that could happen.

Aside:  I assumed that getting the RAWKEY messages from my IDCMP was not
appreciably less efficient than going to the keyboard or input.device directly.
Is this a good assumption?  The IDCMP route is certainly much simpler, but
I need quick response (it's a game, after all).

Any insights appreciated.
