Css errors as warnings in Visual Studio 2008

so finally Microsoft gives us the option to unclutter our errors window and leave out HTML, CSS and Javascript errors (or more usually supposed errors such as invalid css syntax for ie hacks). And helpfully by default, VS 2008 comes with this setting turned on. Great! 

But then, how come my CSS errors are still showing as errors then??

Right, so the problem is that even though VS 2008 installs with the show HTML and CSS errors as warnings by default, only the HTML setting gets set in the registry for some reason. So what you have to do is untick the box where this is set, save it, then tick again, thus manually turning it on so it starts behaving correctly.

To do this, go to:

Tools->Text Editor->HTML->Validation->untick "as warnings (HTML,CSS)", hit OK. Re-open the tools menu navigate to the same place again and tick that box again. hit OK and now things work the way they should've always done.
