Run quirks mode in one frame and standards mode in another?

Question

I have an old application that uses frames (not iframes) was was written back in the IE6 days so it runs in quirks mode.

Is it possible (Using IE 7 or 8) to have one

Answer 1

See my answer here for MSDN-documented solution for IE9: How to force Iframe to run quirks under a standard parent frame

In short, it is not possible to trigger quirks mode in a frame (or iframe) if the parent page is rendering in IE9 mode, but it is possible to trigger "quirks mode emulation" embedded in the IE9 rendering engine.
