VS2008 SP1 and the missing Toolbox controls

I recently upgraded my VS2008 installation to the new SP1 release, I found that several of the .Net controls disappeared from the ToolBox, including the Button.

A new Toolbox also appeared labelled "#13119" with nothing in it.

To resolve this issue I had to delete the cached version of the Toolbox in my User profile, then when restarted VS2008 recreated the Toolbox and my missing controls reappeared.

Sorted :)
