I am trying to diagnose a problem with an internal production application.

We have SharePoint 2007 with a content editor page that hosts an iframe.

Inside this iframe is a simple aspx web page that displays a table of comments and lets you add more comments.

The comments are inside a textarea.

Parts of the comment gets duplicated on display.

I am testing with a comment “1 2 3 4 5 6 7 8 9 …. 35 36 37 38 39 40”

Static View of the Rendered textarea

You can see the first line runs to 25 then wraps to the next line and starts back over at 19.

The actual HTML source is correct.

If I view the page directly, instead of from inside the iframe in sharepoint, it renders correctly.

If I create a test web page with an iframe showing this content, it renders correctly.

Firefox renders correctly both the SharePoint site and the test web page.

I have tried several search terms and google, but to no avail.

Showing the Highlight Error

I have only reproduced the error on Domain Computers (XP and 7) with IE 8. I have not tested with IE 9.

Using a basic install of XP and IE8 on a VPN to the corporate network renders correctly.

Any ideas on this problem and how to fix it? Could it be a GPO Policy causing the problem?

——- UPDATE ———-

Using the Internet Explorer tools, I have determined that the page will render in IE 8 correctly. It does not render correctly in IE7 or IE8 Compatibility Mode.

Internet Explorer 8 renders intranet pages in IE8 compatibility mode by default.

    I added <meta http-equiv="X-UA-Compatible" content="IE=8" /> to the head of the page to force IE8 not to switch to compatibility mode for an intranet page.

    This does not fix the issue for IE 7
