Hi guys,

I've taken a look through the forums but can't seem to find any mentions of this before.

In Internet Explorer 8 on Umbraco 4.0.3 (and 4.0.2.1), when inserting an image through the Rich Text Editor, the following occurs:

1. I can select an image from the media library.
2. When I select an image the Url, Name and Dimensions fields are filled in, and a thumbnail appears in the box.
3. When I click the Insert button, the pop-up seems to refresh, and the fields are all reset to blank.
4. The image is not added, and a Javascript error appears (I'm not sure if this is a symptom or a cause):

This happens on production and development environments in IE8. I haven't tested in earlier versions of IE, but it's working absolutely fine in Firefox 3.

Any ideas? I've asked my client to use Firefox for the time being, but would really appreciate a fix of some sort.

Thanks!
