God helps those who help them selves :-)

Just thought I'd post since I've just resolved the problem that I stated in
my original thread.  The problem was with LoadIcon retaining the orginal
handle when trying to reload icons.  I found the answer when searching
google out of desperation.  MSDN states that:

"Note  This function [LoadIcon] hase been superseded by the LoadImage
function."     <- please note, the spelling mistake ('hase') was MS's not
mine :-)

which got me looking carefully at LoadImage which seems to always retrieve a
new handle, regardless of whether or not the resource has been loaded
before.  I've replaced all LoadIcons with LoadImage - and lone be hold, when
you change the screen resolution - all the correct icons are displayed.  Got
there in the end :-)
