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

I’ve had some trouble accessing 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 domain and now I can access again.
