on this page its not possible to click into the text fields: http://www.regele-arkanum.de/html/newsletter.html. This happens only with Firefox (14), with IE its ok.

Deactivating Javascript helps also. The problem seems to be in the javascript created for the navigation bar. I have tried different settings without success.

I use NOF9 but not sure wether this issue is a NOF9 issue.

Does anybody have an idea on this?

Any help is appreciated!
