modal popup error - cant set focus to control

Hi

My webpage contains a modal popup. I am using the atlas release - the june ctp i think

I'm getting an error on my webpage if I view it in Internet Explorer 6. This is the error

Can't move focus to the control because it's invisible not enabled or of a type that does not accept focus

I get this error on page load. Everything works fine but naturally i dont like the error message.

I would really appreciate it if you could take a look and shed some light on it for me

I checked your website and did not see any error message. Everything works fine.
No issues here with IE6 or Firefox 1.5.0.8.
