Troubles in Blogger paradise

I tried a few blog postings with the mail settings but unfortenately I used HTML and Outlook. A lot of overhead in the code of those post as a result: not to say a lot of sh**!
Now I can't publish anymore on a correct way: I always get a time out error despite the content is published to my own domain name!

I looked into the template code and removed a lot of old scripts referring to other sites. The mean problem was that this blog was visisble with Firefox but NOT with Internet Exlorer!?

Now it seems working again. Strange. Can't find a good explanation, however...
