Thanks!
Well for this page:
http://homepage.ntlworld.com/bobosola/pngtestfixed.htm
It's no fix in my IE6-browser. The transparent part just gets grey -like no png-fix.
For this page:
http://www.twinhelix.com/css/iepngfix/demo/
The first png gets all blue. The second disappear in my IE6.
On this page:
http://jquery.andreaseberhard.de/pngFix/
The first four pngs are gone, after that it's two showing with grey.
So it's not every png missing..
Anybody having a clue?
