IE quirks mode problem : all source on one line

Hi,

i'm having an issue with CKEditor 3.1

I know quirks mode is no good but sometimes you don't have the choice (existing pages), so I included a CKEditor 3.1 on a page in quirks mode (no doctype at all).

All works fine with all browsers but Internet Explorer.

When pasting HTML in the Source mode, all html is rendered on one line and when you press "Enter", a space is added, no way to go to a new line.

Adding a quirks doctype in the config.docType did absolutely not change a thing.

I easily reproduced the problem by removing the doctype line on the _samples/fullpage.html file. The sample is attached. Save it in the _samples/ folder and load it in IE. The textarea contains HTML with line breaks. Click "Load CKEditor" button and all the HTML goes on one line, and no way to add a line break.

What can I do to make it work properly please ?

Thanks
