lightbox++ overlay solid black in Internet Explorer 7

[nlawson2004]

On this site I'm working on [site name removed by OP request]
on the PRINT page,
lightbox++ runs correctly in all browsers, except that in INTERNET EXPLORER 7, the overlay is completely black, in other words it's not 'see-through', it's not transparent. It's transparent in Fire Fox and Safari.

It's being called with AS3 from a swf, if that means anything.

I've searched up and down to no avail.

Any help is greatly appreciated.

what lightbox script did you use? is it from the dynamicdrive?
please include the source code, so we can test it too.
