You probably know by now.  Microsoft has announced the release of Visual Studio 2008 Beta 2 and Visual Web Developer 2008 Beta 2.  The release incorporates improvments to Javascript intellisense, apart from making Javascript errors available through the error tab.  I will probably write more on this later.

Meanwhile, Alex has written about an installation problem in which might lead to non availability of these features in Visual Studio, and the workaround for restoring the full functionality.  The issue lies in the Jscript engine not being registered peoperly.  In case you hit such a problem, check out the blog here.
