Google Docs.. The Good News and The Bad News..

We were working with a Google presentation, and all of a sudden google docs crashed hiding the document, with the message,


The bad news is that Google Docs has just encountered an error.
The good news is that you've helped us find a bug, which we are now looking into.
We apologize for any inconvenience this has caused you.
In the meantime, if you'd like updates on this and other issues, try visiting our Google Docs Help Group: http://www.google.com/support/forum/p/Google+Docs

Sorry, and thanks for your help!
