I've noticed some other quirks with Netscape 7. It seems to have problems when I try to log into certain sites, such as deja.com or even sourceforge.net. I can still get in with Netscape 4.x, however. I checked the preferences, but all looks normal so I haven't a clue what the problem is.
On a completely unrelated note, wasn't the G5 supposed to be out by now?
