EXACTLY! Hallelujah! It finally works again! I have no idea why, but who cares.
Just in the nick of time too, since my new online banking site (I decided opening a joint account with my new TIC partner would be a good opportunity to switch my personal accounts too) doesn't like Safari. Their tech support was actually very responsive. But when I told them my text settings were not causing the problem (see gigantic navigation buttons filling the entire screen below), they told me what I knew was coming all along. The problem is I'm using a Beta version of Safari. (Or at least, that's their out.)

They suggested I use Firefox, or revert back to Safari 2. Obviously, I'd rather slit my wrists than revert back to Safari 2. So I gave Firefox another go.
Amazing. I have another lease on life. If only I could find the time to have a life...
Yay, I am on TV... I mean screenshot!
I am so happy that your opacity has returned to normal!!
