Vista - sign in to trusted websites

I am not able to post a thread on one of the websites that I have added as a trusted site on my computer.

I sign in immediately after visiting the site. After that I am asked to sign in again to allow me to post a message. The same screen shows up repeatedly after I put in the same info I used when I started. It doesn't indicate that the password or the name is incorrect.

The website was contacted for assistance. Their solution was to delete all temporary internet files which was done, but it didn't help.

I am posting my question here because it is a problem with my computer, not their site.

Can anyone help with this problem? It does seem to be a bit strange that since I am signed in that I would have to sign in to post a message on the forum. A bit redundant.

Thank you.

Open internet explorer, tools> internet options>security. Highlight trusted sites and click on default level. Restart internet explorer and try

Thanks for your reply. I tried it, even though I had the security level on low and the default setting is medium, and it didn't work.
