It is extremely annoying. When logged out, everything works. When logged in, nothing works.
I suggested many months ago that they quit trying to be clever with menus and just put in plain, static, HTML links...that would fix it for everyone.
As it is now, I cannot edit or even depot submissions.
I have to log out, navigate to the correct item, copy the URL, then log back in, paste in the URL, then edit it.
Plain HTML links would solve this permanently. Please please please please.
BTW - its not a firewall issue, nor a cookie issue. Happens on computers that have never been to this site before, not OS dependant either, not related to MSIE security settings. I've checked all this.
