SYMPTOMS
========

When the Active Desktop is enabled on your computer, some wallpaper bitmaps may
not display correctly if the wallpaper display mode is set to "Stretch". In
addition to multiple horizontal bands of distorted desktop background, dragging
or resizing windows can result in additional erratic scrambling. Note that this
problem is only likely to occur at higher screen resolutions when you are using
the "Blue Rivets" or "Triangle" wallpaper bitmaps (both of these are 16 x 16
bitmaps). Note that if the Active Desktop is disabled, the desktop does not
attempt to display the affected stretched bitmaps.

CAUSE
=====

This problem can occur because the Active Desktop Web content display
(Mshtml.dll) fails to properly handle an unexpected error from the Graphics
Device Interface (GDI) function "StretchBlt()", and this results in the display
of improperly-filled bitmaps on the desktop background.


RESOLUTION
==========

To work around this problem, select a different background picture.

STATUS
======

Microsoft has confirmed this to be a problem in the Microsoft products that are
listed at the beginning of this article.
