Adobe Reader in IE11 grays out displayed document when another PDF is downloaded
We are using latest Adobe Reader X (11.0.10), and IE11 uses the same to display embedded PDF files.
There is a simple HTML file which embeds a PDF using iframe, and it gets displayed fine on IE11. But on that same page if we just try downloading another PDF file, then as soon as that download is over, the currently displayed PDF gets greyed out.
The HTML code is:
<html>
<head>
<script type="text/javascript">
function dl() {
location.href = 'pdf-dl';
}
</script>
</head>
<body>
<h1>Test PDF</h1>
<iframe width="500" height="500" src="pdf-inline"></iframe>
<br/>
<button type="button" onclick="dl()">Download</button>
</body>
</html>
Here "pdf-inline" URL sends the PDF content with following response header:
Content-Disposition: inline;filename="test.pdf"
And "pdf-dl" URL sends another PDF content with following header (this forces the file to be donwloaded instead of being displayed inline):
Content-Disposition: attachment;filename="another.pdf"
We have already tried many options, and none of those work:
- Set "TabProcGrowth" registry entry
- Disabled all protection in Adobe Reader preferences
- Tried downloading same PDF instead of another one
Things that worked:
- Upgrade to Adobe Reader DC - it works! Unfortunately, we can't upgrade Reader for current users.
- Using Chrome - it uses its own PDF renderer and so no issues.
Another observation is that if we download something else (e.g. zip file) instead of another PDF file, then it works fine. The issue happens only when 1 PDF is already displayed and tried to download another PDF.
Please help.
