CSS Problems Mozilla
In reworking the Scribble Show page to use CSS for layouts, I discovered that Mozilla is very strict with mime types. Many servers (including the one from which these pages are served) are not configured to send a proper MIME header for .css files.
If your page has the doctype set so that Mozilla decides to use "strict" render mode (See view-> PageInfo-> Render) rather than quirks render, your CSS will not load if your server is not configured properly! So if you read the source of the page you are currently reading, you will find no doctype tag - it was easier than fiddling with my server. =)
