VS2005 pretty unstable with the Orcas CTP ?

I've crashed VS2005 out many times since starting to play with WPF, is it known to be generally unstable? There is something over at the Register implying that maybe it is, and that we won't see fixes for some time?

For example I downloaded an WPF example from

And can consistently crash VS2005 with it
