Ok, I have a webpage. Looks fine in Firefox, MSIE 7, etc. But MSIE 8 barfs it into a horrible mess.
BUT! It shows me a button called "Compatibility View" that magically fixes the problem.
... That's great and all, but I'm not about to go telling our clients to click their "Compatibility View" button to fix the problem. How can I tell what MSIE 8 is doing in "Compatibility View" mode? Is there a way to highlight in the HTML/CSS/JS source code what it thinks is the problem for compatibility?
