    <description>&lt;P&gt;In IE 11 browser, When try to open a window with Dropbox authentication page for Dropbox Chooser,&lt;BR /&gt;
We are getting the error "Unable to communicate with parent window" in the authentication window. &lt;/P&gt;

&lt;P&gt;We are using the following code :&lt;/P&gt;

&lt;PRE&gt;&lt;CODE&gt;               var options = {
                    // Required. Called when a user selects an item in the Chooser.
                    success: function(files) {
                        var docName = files[0].name;
                        var docExtension = "";

                        if (docName.indexOf(".") != -1) {
                            var tmpNameArray = docName.split(".");
                            docExtension = tmpNameArray[tmpNameArray.length - 1];
                        }
                    },

                    // Optional. Called when the user closes the dialog without selecting a file
                    // and does not include any parameters.
                    cancel: function() {

                    },

                    // Optional. "preview" (default) is a preview link to the document for sharing,
                    // "direct" is an expiring link to download the contents of the file. For more

                };
                var button = Dropbox.createChooseButton(options);
                Dropbox.choose(options);
&lt;/CODE&gt;&lt;/PRE&gt;

&lt;P&gt;and the following script is included in the jsp :&lt;/P&gt;

&lt;P&gt;&amp;lt;script type="text/javascript" src="&lt;A href="https://www.dropbox.com/static/api/2/dropins.js" rel="nofollow noreferrer" target="_blank"&gt;https://www.dropbox.com/static/api/2/dropins.js&lt;/A&gt;" id="dropboxjs" data-app-key="&amp;lt;APPKEY&amp;gt;"&amp;gt;&amp;lt;/script&amp;gt;&lt;/P&gt;

      <description>&lt;P&gt;Thanks for the report! First, can you let me know if this does or doesn't happen for you on &lt;A href="https://www.dropbox.com/developers/dropins/chooser/js" rel="nofollow noreferrer"&gt;https://www.dropbox.com/developers/dropins/chooser/js&lt;/A&gt;? If it doesn't, can you provide a sample page where it does reproduce?&lt;/P&gt;

&lt;P&gt;Anyway, one way this can happen is if window.opener is null. Can you open the console on the Chooser popup itself when in the broken state and see what window.opener returns?&lt;/P&gt;

&lt;P&gt;Also, is your site telling IE to use a particular compatibility mode? This can cause issues if the host page (your site) and the Chooser (which is hosted on our site, which tells IE to use the latest mode) are in different mode&lt;/P&gt;

&lt;P&gt;Finally, another thing that can sometimes cause issues is IE's security settings (in the Security tab of Internet Options). Have you made any changes there? Is "Protected Mode" enabled?&lt;/P&gt;</description>

      <description>&lt;P&gt;Thanks for your reply.&lt;/P&gt;

&lt;P&gt;I have check with the following cases and listed the results :&lt;/P&gt;

&lt;UL&gt;
&lt;LI&gt;can you let me know if this does or doesn't happen for you on &lt;A href="https://www.dropbox.com/developers/dropins/chooser/js" rel="nofollow noreferrer"&gt;https://www.dropbox.com/developers/dropins/chooser/js&lt;/A&gt;?&lt;/LI&gt;
&lt;/UL&gt;

&lt;P&gt;With IE 11 its working fine but with the IE 10 its not working.&lt;BR /&gt;
Anyway, one way this can happen is if window.opener is null. Can you open the console on the Chooser popup itself when in the broken state and see what window.opener returns?&lt;BR /&gt;
window,opener is returning null&lt;BR /&gt;
- Also, is your site telling IE to use a particular compatibility mode? This can cause issues if the host page (your site) and the Chooser (which is hosted on our site, which tells IE to use the latest mode) are in different mode&lt;/P&gt;

&lt;P&gt;We have this meta tag added &amp;lt;meta http-equiv="X-UA-Compatible" content="IE=edge;" /&amp;gt; and manifest="ie11WebSite.appcache" added in the html tag&lt;BR /&gt;
- Finally, another thing that can sometimes cause issues is IE's security settings (in the Security tab of Internet Options). Have you made any changes there? Is "Protected Mode" enabled?&lt;/P&gt;

&lt;P&gt;We have tried with both Protected Mode enabled and disabled. We faced the same issue.&lt;BR /&gt;
Do we need to add anything in the html to fix this ?&lt;/P&gt;</description>

      <description>&lt;P&gt;Thanks! The issue with IE 10 on the demo sounds like a different problem so we'll look into that separately. &lt;/P&gt;

&lt;P&gt;Since the demo does work in IE 11 for you, it sounds like there's an issue with using the Chooser with your site specifically. Please open a ticket with the details for your site (i.e., where we can reproduce the issue) so we can look into it specifically:&lt;/P&gt;

      <description>&lt;P&gt;Hi Carol, if you're seeing this issue with a third party app, please contact the developer so they can look into it. They can then contact us with the relevant technical details if necessary.&lt;/P&gt;
&lt;P&gt;If you're seeing this on the&amp;nbsp;Dropbox web site itself, please contact support with the details:&amp;nbsp;&lt;A href="https://www.dropbox.com/support" rel="nofollow noreferrer"&gt;https://www.dropbox.com/support&lt;/A&gt;&lt;/P&gt;</description>
