I'm not suggesting that this is something MSFT has done Deliberately
I think it was sloppy Web page authoring, but I suspect a lot of sites have sloppy
work..
I think that Windows XP. and probably the Linux distro I use have been changed to
ignore many Web authoring Mistakes. The User doesn't have as much impact on his web
surfing.
Since all three Browsers on My XP computer, and 3 mostly Different Browsers work
in a Suse Linux install it appears something in the Operating system allows the Browser
to render the Bad written Web site.
