I'm having all kinds of problems with the backwards compatible plugin your team has released.

I'll load both jquery.1.4.js and the compat plugin.

The first error:

It produces "windowData" is not defined. 

If I comment out your jQuery.data function and reload the page, then the jQuery.fn.init causes the whole page to become a single event, which triggers a "Want to bookmark this page" in Firefox.

If I comment out the jQuery.fn.init function, then the page half works, and causes even more errors.

And firebug isn't showing me the solution...

Unfortunately I had to take down the demo page, as the client wants this fixed yesterday, which means sticking with blockui and 1.3 which I hate to do, but until this is fixed, or I fix it, I don't really have any other options.

Thanks

Marcus

P.S. I'm hoping this is an issue with my code, or the way I've coded something...
