Thank you Jan and Bernhard!!!

Now I made myself an account there and found the description:
-----
When no <base> tag is set in a page containing a JSMENU then an
JS Error occurs in Firefox 1.0.3 when selecting a select-box entry.
The line in question is:
if (document.getElementsByTagName("base")[0].href != "") {

The problem is if there is no Tag named "base" then the .href
operator will fail.

Thars great, but how do I implement it? Can I do it easily by my
self? I have never done something like this before...  :-(

The solution is a "unified diff". Could I just manually remove
the lines with a minus sign from the original js-file and add
the ones with a plus sign? Or?
