I may have confused the issue somewhere along the way,
if so I am sorry.  I am trying to make a window that
looks like a Win9x Explorer window in 'view detail'
mode.  I am assuming (possible incorrectly) that
Windows gets it's icons from shell32.dll, that's why I
was using those icons.  I thought that all of the
Windows 'default' icons are kept there.  When Windows
displays the icons they look correct.  When I display
them in my app they look wrong.  That's why a put a
screenshot on my website, to see if other people get
the same results.  So I am thinking that either
Windows gets it's 16x16 icons from somewhere else or
it manipulates the 32x32 in some way that win32lib
doesn't.  Chris cafromsw at yahoo.com
