Well, I guess la-la land wasn't a very technical description.
Safari doesn't "hang" in the sense that you have to force quit it. I can close it out regular. But the page goes blank and gives the spinning wheel. If you use any safari preference (reset safari, private browsing, etc), the preference window grays out when you click the "ok" button, but the preference doesn't change...if that makes sense.
So say I select private browsing....the private browsing message window turns gray, the window doesn't close, private browsing is not initiated, and you have to close out safari...but you can close it out the regular way. No forced quit is required. Same thing with any other preference change.
As far as browsing, every initial page loads fine. But about 50% of the time if I click on a sub-link contained in that page it goes blank and get the spinning wheel.
It's just weird behavior.
