[ubuntu] 12.10 Hangs every time

So I want to give 12.10 a try, but I can't get it installed in virtualbox. I've tried dozens of Linux Distros in Vbox and I don't know what the issue is. When I click continue to install it hangs. The little circle sits there spinning. Also, sometimes Virtualbox starts running my processors full blast. And I haven't found a way to stop it except for restarting. Does anyone have a work-around or a suggestion. The .iso is fresh straight from ubuntu.com. I've tried the download and torrent.

Thanks,
