<br>The only difference i see in Fiddler is with internet explorer there is a "storePNGInSession" and with firefox/chrome not. Is this a setting/script or bug?

Hi,
the error message is clearly a bug, but the behavior, no preview for crystal reports in internet explorer, is intended. To render the preview we usually use a javascript pdf viewer, but this only works with current browsers. For internet explorer, as a fallback we try to render the first page as an image - but unfortunately crystal does not support rendering as an image. So we will fix this, but there will still be no preview, but only a nicer error message to the extend of "no preview available". Perhaps we will support the use the adobe acrobat plugin, if installed, later.
Cheers,
Thorsten
Ok, thanks for the quick reply.
