I have one computer where I still have 3.6 or the beta available. It
defaults to 3.6. I have to manually start the beta. The other
computer seems to have "upgraded itself" as harrygreen claims. I
never downloaded or installed the beta and I don't remember seeing
anything asking me if I want to install it. It doesn't really bother
me me, but it's curious none the less. As far as the "back" button,
I've found that if I right click it, it gives me a choice of all
previous pages to choose from. Hovering over it doesn't seem to make
a difference. It still just says "go back one page." What OS are you
using? I'm running Kubuntu 10.10, 32bit. (I was using the 64 bit,
but found certain programs wouldn't work and I had problems on the web
wtih certain embedded videos playing like on Yahoo for example.
