Although I generally use Firefox for my browser, last week I was facilitating an Edublogs workshop for the Area 3 Writing Project and noticed an issue with embedded files when viewed in IE: the files appear as blank boxes and no amount of clicking can activate or open them. So I turned to the EB Forum and found the solution: Use Firefox!
But if you must use IE, here’s your workaround: Same as always, you will need to copy the embed code from the media site and then open the HTML editor of your post or page. Put your cursor where you want the media file to appear and paste in the code. Then click on Publish or, if you’ve already published this page or post, click on Save. Do NOT go back into the Visual editor. For some reason, with IE, if you head back into the Visual editor, the embed code changes, which is not good.
I’ve updated the Intro to Edublogs Manual to include the embedding issue – and also added instructions on adding a hyperlink to a comment. Here’s the linik: http://blogwalker.edublogs.org/files/2008/08/edublogs_08-14a3wp1.pdf.
