IE6 - click created Control.window href problem

I have a Control.Window exactly like the Centered Window / Content on Page example on livepipe.net. In IE6, the code fails to find the div with the content and so ends up creating a blank hidden window. The problem lies in this line of window.js:

var rel = this.href.match(/^#(.+)$/);

in Control.Window.initialize

In IE6, the line before it

this.href = this.container.readAttribute('href');

returns the full url of the associated A tag - not just the part in the href='#..' attribute.

So this.href = /

not

this.href =

and so the match fails

I changed the match line to

var rel = this.href.match(/^.*#(.+)$/);

and that should cover all the bases no matter what browser is in use
