I access hotmail via a shortcut I put on my browsers 'Links' toolbar.
A day or so ago this shortcut ceased to work for some reason. So I accessed hotmail directly, signed in and made a new shortcut to replace the existing one on my Links bar.
So far everythings back to normal. Seems the URL changed for some reason.
Incidentally hotmail is the only service I have, no Live toolbars or any other Live junk.
