Is it possible to make IE6 (or IE 8 set to quirks mode through the IE Developer Tools window) load and show a Bing Ajax version 7 map control?
For example, try running the "Hello World" example on this page in IE6 or IE8 in quirks mode. The page remains blank.
From this blog post I understand that the Bing Ajax v7 map does not officially support IE6. But you can visit maps.bing.com with IE6 and it shows a v7 map, so it must be possible.
I've played around in IE8's Developer Tools window and if you suppress the position style element on the div with class MicrosoftMap that's added dynamically by MS's JavaScript it starts to look better. This makes me think there's some magic combination of styles on parent divs and other tags that will make it work.
