Alex, I think you have nailed it!  Everything I have read so far
indicates that an exception will be thrown whenever attempting to
write outside of a window, subwindow or pad.  So it would appear to
follow that if for some reason I need to write something to that very
last cell I will have to handle the exception generated.

Thanks!
