I can login fine using IE and FF, but with Opera when I get redirected back from the Google login page, I'm still not logged in. I looked through the tips at I Cant Log In With My OpenID Troubleshooting Tips but they don't apply or seem to have no effect on my setup (which is quite vanilla, actually). I'm using Opera 9.64 on Vista... any further troubleshooting tips?
Edit: The Vista system is a work computer. At home I run Opera 9.63 (almost same version) on Ubuntu 9.04, and this issue does not occur. I'm pretty sure my home system has similar preference settings (cookies etc). I also have a VirtualBox setup with a Windows 2000 system, with Opera 9.62 on that also (can you tell I like Opera?) and that setup also works. I upgraded both of these to 9.64 and I can still log in without issue.
