I'm running a Mac OSX 10.5.8 While pages load well, several perfectly normal features don't seem to function. The "back" button is shaded out and unusable after you have arrived at a web page, and you need to have another tab open to switch between to activate it. Same thing with forward. Also most standard links on web pages are no longer colored and underlined, though the option for that has been selected in the preferences. Links still function, but they are in black without underline and are thus difficult to distinguish from other text. The cursor also becomes the text-editing cursor rather than the hand cursor when you hover over a link.
