Yes, Wiebe Baron on 20 Feb 01 posted some changes that worked in Win2K.
He used FFI to talk to the Win32 API, making the desktop transparent (and 
letting the OS handle its transparency). I guess the windowing system has to 
know about layered, transparent window areas; apparently Win2K does.

 He said:

These attachments do something like that ;-)

Win32SqueakMorph                simple version for 2.8 & 3.0
Win32SqueakNavMorph     Modified ProjectNavigationMorph for 3.0 only

They allow squeak windows and morphs on the desktop, seemlessly (eh...)
integrated with M$'s windows.

Several points:
- This only works with Windows 2000.
- This will bring your PC to it's knees (there is a better VM solution)...
- Mouse & painting redirection is not needed, events are automatically
passed through trasparent sections to the desktop :-)
- Squeak's display mode should be set to 8 or 16 bits, 32 doesn't seem to
