I tried again with r3035 with 32-bit Vista and 64-bit Windows 7 and indeed 
cloned windows behave well on both. I will repeat the test tomorrow with the 
same computer I had issues with.

I have used such a system 15 years ago and it was pretty nice to use but 
somehow expensive because it was built on top of ArcInfo, ERDAS Imagine and 
Oracle.  

For the real work vector layers could well behave like they do now but there 
should be a way to control individually the visibility of the background 
rasters.
