For quite some time now, we have been getting sporadic reports of mysterious login problems, mostly with Internet Explorer but sometimes with other browsers on other OSes.

Help by answering the following:

1. What specific browser and OS has the problem? (including Major / Minor version)

2. Does another browser on the same OS have the same problem?
3. Does the same browser on a different OS have the same problem? You might not be able to check this, but for example if you are on Windows, and trying a
4. Linux Live CD is not a problem for you, then please try.

5. Does the browser have any toolbars/spyware that could be interfering?
6. Does clearing cookies/history/files help?
7. Does a browser reinstall help (if the browser is OS-bound then an OS reinstall)?
8. What other troubleshooting measures have you tried?

Full Story.

EDITOR'S NOTE: Instead of my visitors reporting on the Drupal forum, I think it best if they answer in comments here. Afterwhich, I will compile the answers and submit them to Drupal. Thanks.
