Summary: function/cursor keys don't work

Engineering.
I have been using Dave Wecker's VT100 program (v2.3, 861101), and have 
found that the function keys (including arrows) do not seem to work reliably.

If I hit the cursor keys SLOWLY (ie, maybe wait a second between successive
keystrokes), things usually work ok.  However, if I hit the keys a little
bit more rapidly, or just hold one down, VT100 invariably gets sick
and splatters lots of garbage out.  Usually this garbage consists of a 
a single character repeated over and over -- usually I'll get the letter
"U" printed many times.  Usually after it spits out enough characters
it stops and things work again (as long as I don't use the arrow keys).
Sometimes it just spits out the character seemingly forever; other times
the system freezes and I have to exit the program (that hasn't happened
many times though and I can't remember if VT100 still exited neatly via
the close gadget or whether it required a reboot to kill the process).
This same behavior is shown by the other function keys.

The compiler doesn't seem to be at fault this time -- both Lattice 3.03B and
Manx versions of the program do the same thing.


Does anybody know what the problem might be?

Also:  some people have complained about the visible beep option not working.
       That DOES work just fine in my version (I edited vt100.h to set
       default beep volume to zero).
 
Oh yes -- I *did* edit vt100.h to make sure the #define LATTICE and
          #define MANX were set appropriately for the compiler being used.

Other than for this one problem, the program seems to work really well;
overall I am extremely pleased with it.  I just wish I could use my
functions keys with my editor!
