Moodle Vanguard :: Blog :: Powerpoints in IE7 load with a blank white slide

We are still struggling with the powerpoint problem loading a blank white slide in IE7.  I really think this is a browser problem, and I had hoped it would disappear with the first service pack.  We still seem to have the problem!  This is how I will attempt to fix the problem:

 resource.class.php

605-616 in my file, because I added some comments.

echo '</div>';
echo "<div class="popupnotice">(<a href="$fullurl">$fullurl</a>)</div>";
}

//add this code to force download string to be appended to all ppt resources
//because IE7 will only show a single blank slide when linking to a presentation
if($mimetype=="application/vnd.ms-powerpoint") {
$fullurl=$fullurl."?forcedownload=1";
}

redirect($fullurl);
}

Essentially, this method can be realized manually by adding
?forcedownload=1

To the end of every url as you link the resource in moodle. The problem with that method is that it requires a lot of work if you have to do it to very many powerpoint links.

One of our faculty members might have figured out another fix:

"Need to add moodle.mcm.edu to Internet Explorer's trusted sites. Just allowing it to download the file results in the single blank page issue. "
