FIXED: From Tom: If the display gets reset and you re-initialise it by pressing
	a button (ie.  default event) the re-init is not quite the same.
	I think the wrap mode is not re-initialised the same.  I think
	wrap mode is actually turned off very early by one of the
	startup messages.

SIMM compatibility - This might be fixed... need more testing and
	feedback from users with problematic simms --- this is
	looking pretty good now :)

Audio glitch at start of song (silence to playing data transition)

Audio glitches in the middle of songs... seemingly random.  Is this
a simm compatibility problem?






Serial output stops.  Eg, you see this (added 't' to redraw_time):

This might be fixed now, due to the excellent suggestion from Svet:

The missing data went into the serial Tx buffer but the interrupt
routine never sent it, and once the buffer filled the Tx timeout
sanity check reset the buffer.  Why does this happen???
