Is it just my interpretation of what it does, or does the compatibility mode mean that they just switch back to the old way of breaking things rather than the using the new way they've devised?

Compatibility mode = IE7 mode (or worse).

So yes.

Interestingly I just viewed a page I'm working on in Compatability mode then in IE7 mode using the developer tools. The rendering was different. It looked fine in compatability mode but in IE7 mode it required the usual "has layout" fix to work. In theory that means compatability mode is a waste of space for testing purposes because the page could still look wrong in IE7.

Well, as if it's not bad enough designing something which never works correctly, it sounds like they can't even break things consistently now.

I fired up a machine with it on for the first time last night, and ended up prepping an IE8 fix stylesheet within about sixty seconds of using it. I was wondering if I might just have been unlucky. It would appear not.

Did you try setting the browser mode to IE7 in the Developer Tools?

Yes, thats the whole point. Its possible to design a site that works in compatability mode but doesn't work in IE7. In other words, IE8 in compatability mode does not render the same as IE7 or IE8 switched into IE7 using the developer tools. Its probably the case that IE8 in IE7 mode is not identical to the real IE7 either which really confuses the issue.

Compatibility mode is not meant to be IE7.

IE8 made, with the developer tools, to act like IE7 should act like IE7 though.

Just for chuckles, I found this post in that blog entry you linked to awfully amusing.

Just for future reference with regards to forcing mode with IE8, it appears that using the meta tag doesn't disable the compatibility mode button whereas issuing a direct header does. What i've read seems to suggest both will work, but only the latter did in my case.

header('X-UA-Compatible: IE=8');
