DD IE PNG with Ajax Modal Window

Hello all,
Currently i'm using DDIEPNG (http://www.dillerdesign.com/experiment/
DD_belatedPNG/) as my IE6 png headache pill, but i hit a problem with
ajax modal window....

I'm trying to create modal window using lightbox gone wild tiny js
script (http://particletree.com/features/lightbox-gone-wild/) with a
little tweak that suit my problem... and it create modal window
"content" on the fly base on the url given to lightbox... but it's
seem DDIEPNG can't parse the new content base on ajax call....

R there any solution regarding these problem ?, or do i need to use
another PNG fix js ?
