Internet Explorer 8 with linked Reader XI doesn't display png images

Hi,

we've got this problems:

When you use applink with IE8 as main process and Acrobat Reader as Plugin, you cannot see .png images on web sites using IE8. See picts below:

Removing Acrobat reader from plugin folder, the .png images are displayed with no problems.

The bug occours both on Win7 and WinXP using an internet explorer 8 and acrobat reader captured on a full clean vm XPSP3 with ThinApp 4.7.3 (I’ve got the captures). Both packages are created with default options with no customization.

Any suggestions?
