Your crystal ball is correct.  The empty watch pane seems to be triggered 
by:
  unsigned char tempc;
Initializing tempc to a 7-bit value fixes it; initializing to a value with 
the high-bit set breaks it.  It doesn't matter whether the unsigned keyword 
is present or not.

Thanks for figuring this out.  Debugging with a broken debugger is not fun.
