Slashdot Menu: Opera: Works on HDD, but not on Server

[t_anjan]

1) Script Title: Slashdot Menu

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex1/slashdot.htm

3) Describe problem:

The menu works on Opera when on my HDD. But when I upload it to my server, the menu doesn't respond at all on Opera. It works fine on the other browsers. What could be the problem?

The menu works properly on the Dynamic Drive page also. Is there any setting I have to activate on the server?

Thanks!

Answering my own question:
I had the "Mask as Mozilla" option on in the "Site preferences" for the domain in question.

Apparently, the "Mask as Mozilla" option does not gel with this script. As soon as I switched the setting from that to anything else, the menu started to work. Even "Mask as IE" worked.
