Editor is loading up in IE7 without contents

[Martin Kou]

To reproduce the issue:

1. If you don't have IE7, install IETester and open an IE7 tab in it.
2. Delete all temporary internet files in IE7.
3. Go to ​http://nightly.ckeditor.com/3561/_samples/replacebycode.html.
4. The editor instances appear with no contents.

This bug is very tough to even reproduce...

1. It seems to be only reproducible with distant, high latency servers (ckeditor.com is in Poland while I'm in Hong Kong, so the nightly server is high latency for me) - if the page is in the local machine or even in a low latency server then it can never be reproduced.
2. It happens the most with IE7, occasionally with IE6 and I've never seen it happening in IE8.

When the bug can be reproduced, the HTML contents are actually added in the editor iframes. If you double-right-click in where the editor iframe should be, you'll even see a caret blinking.

Also, if I put an alert box in the code, then it would never be reproducible.

The only way I've found to fix this conclusively is to do some CSS changes to force IE into redrawing the contents in the editor iframe.

I'm worrying the '1000ms' might be interrupting.

[Martin Kou]

The 1000ms delay doesn't block any editor operations. All it means is that when the bug occurs, the editor would appear with no contents initially, but after 1 second the contents would appear. So it should be ok.

I'm ok for this fix for now, as it's quite urgent. But, I would ask you to please open a new ticket after committing, to find alternative ways to fix it without delays.

Fixed with [3640].
