One serious one that will stop it working for anyone, and others that may or may not affect most people.

In the comments of the script (the top part where I explain the versions, etc.) each line is supposed to start with a semicolon ; but one line starts with a colon : and it will cause the script to break. OOOOPS!!

So, feel free to edit that colon into a semicolon.

The other bugs are browser related, and I don’t yet have a good solution that works on all major browsers, so… I’m working on it. If you’re having trouble, let me know as it might help me to find a good solution. I will post an updated version as soon as I have it finished.
