DC locked up several times for me yesterday too and Christmas Day (?) it was bombing badly. Tried to edit a post that I'd only just written and it repeatedly threw me to the home page instead.
Pacanis, if you click on the <File>, <Edit>, etc menu at the top, you will see what keyboard short cuts are available in IE, eg Ctrl S for save, etc. I hate needing to use a mouse and since the advent of the internet, I am needing to use one more and more as many pages aren't set up to utilise keyboard commands, other than the very basic ones. Very frustrating!
Too many restaurants, not enough time...
