Status: RESOLVED FIXED

Description

[Nigel McFarlane]

The purple octopus demo of bug 113232 does not maintain
desktop transparency correctly under windows 98. See the
following set of screenshots which show destruction of
proper transparency management.

Transparent regions of a mozilla window should show the
correctly updated desktop and background windows at all
times.
