Hi,
Thank you very much for trying to help and for spending your time testing.
I have now come to the conclusion that these script errors occur because of
restrictions related to the actual homepage and there is nothing one can do
to eliminate them.
Using another browser as standard browser does not make any difference. Web
queries in Excel 2007 is always tied to Internet Explorer and cannot be
changed.

Doing the same web request to other web pages can be carried out without any
problems.
