Hi David,

This works for me using your linked version of XSTRETCH. I am on Mac OS
10.3.9

IDL> print, !VERSION
{ ppc darwin unix Mac OS X 6.2 Jun 20 2005 32 32}

IDL> xstretch, bytscl(hanning(300,300))
% Compiled module: HANNING.
% Compiled module: XSTRETCH.
% Compiled module: LOADCT.
% Compiled module: FILEPATH.
% Compiled module: PATH_SEP.
% Compiled module: TVIMAGE.
% Compiled module: XMANAGER.

I can't tell what the problem might be from this end. Are you having
this problem from the command line or from within a managed routine?
