Grey pdf page in IE after installation of acrobat X

[dvegmond]

Before update adobe adobe acrobat reader version 9.4 to version X i got correct PDF output on the screen. After the update to version acrobat X the pdf gives only a grey looking page using browser Internet explorer 8. It's OK on firefox and google chrome. Does someone has the same experience ? and may me a solution ?
Thanks Daan

Hi, confirmed, I have installed the X version and get the same behaviour in IE. But I have tested the X version on different sites, with different browsers and different features and got a lot of errors with the X version (mostly the pdf viewer freezes) so really no idea what I should think about this version.

Is this some kind of Alpha version, if not then we must wait until there will be some guides how to solve such issues

Hi Jan, i found on the internet the following solution:
Change the following file in libraries/joomla/environment/response.php
JResponse::setHeader( 'Cache-Control', 'no-store, no-cache, must-revalidate, post-check=0, pre-check=0', false );

To
JResponse::setHeader( 'Cache-Control', 'no-store, no-cache, must-revalidate', true ); // Extra CYA
JResponse::setHeader( 'Cache-Control', 'post-check=0, pre-check=0', false ); // HTTP/1.1

That solved my problem, By the way adobe acrobat version X is an official version now. Thanks Daan
