Re: Conflict with Dean Edwards' IE7.js
I tried out your code snippet. It seems the disappearing text is a side effect of your usage of the Shadow filter. I'm not sure exactly why it is doing that, but removing the filter makes the text appear. Of course then you lose your text shadow effect, but at least you can read it
Regarding the link background not being clickable in IE6, this is a known issue which I hope to fix, or at least provide a workaround, by beta3.
