This just happened in the past couple of days. Not sure if it's related to all the extra virus email, to a recent security update, or what. It affects Safari on both user accounts on my G4. By the way, we're running Safari 1.0, under OS X 10.2.6
The regular icons on the right side are still there, as well as the clock, but if I click anywhere in the menubar, it turns blue and sometimes just the help menu will appear.
Can anyone help?
