Hi,
I use the last Ubuntu distribution and with it came a new, but now known bug with flash that can only be fixed by Adobe. I mention this because I have a bug with the menu navigation: the down scrolling menu options get hiddden by the header (wich is probably made with flash) instead of appearing in front of the header.
I apologize if this was already reported (or if you were already aware of it and consider there are not enough ubuntu users :P) I couldn’t find it.
So long
