Visual Studio crash when choosing items in the Forms designer toolbox

Ran into a strange issue with Visual Studio 2008 SP1 where it crashed, vanished with no errors, if I selected the Choose items menu item in the context menu of the Windows Forms designer Toolbox window. Attaching a debugger and reproducing the crash gave me the following error.

I have no idea what has caused this, but closing all Visual Studio instances and then starting it once with the /safemode switch and then closing it seems to have fixed the crash.

Trouble accessing support.microsoft.com

I’ve had some trouble accessing http://support.microsoft.com lately and thought it had to do with me using Firefox, since it worked just fine when using Internet Explorer.† I got an uninformative ASP.NET runtime error.

Server Error in ‘/’ Application.


Runtime Error

But after reading this thread at channel9 I cleared all cookies from the microsoft.com domain and now I can access http://support.microsoft.com again.
