strange behaviour Moz 1.2 on OS X

Hi fellow wyonistas,

I just downloaded Mozilla 1.2. While checking it's behaviour I 
encountered a strange thing. I hadn't the time to figure out why it's 
like that (has to wait till tomorrow). In the demo publications like 
OSCOM or unipublic the drop down menus of the wyona bar (eq. the 
contents of file, search, help and debug) will disapear behind other 
elements of the page. For example in the OSCOM publication the 
drop-downs are behind the orange header and the text (navigational 
and main contents).

Does anybody use Mozilla 1.2 on another platform and encounters the same?

Cheers
