Hayden,
If you really want to solve this problem, you should follow up on the suggestions we have already made. Your approach to ID "cookies" and why you think they are incorrect, is not going to help. This is not the way TBN's or any other cookies work.
I have attached a screencap of my current TBN cookies. There are actually more cookies than show up in this capture, but you get the idea.
You apparently are looking via IE "show cookies" command. That is why I told you about the Karen's Cookie Viewer, because that will locate ALL of the cookies, so you can delete them. Did you delete ALL cookies, then re-login?
If you are using Internet Explorer, you can create a "secure pass" for TBN, by going to the menu bar and selecting "Tools", then "Internet Options." Once that box opens, click on the top menu bar "Security". Once that opens, there will be several icons, select "Trusted Sites". That will open a form box. Type in
www.tractorbynet.com and tractorbynet.com.
This will ensure that IE or Windows itself is not doing the cookie manipulations.
If this adjustment to IE does not help, then if you could install -- just for this "test" -- the current version of Firefox browser.
Once Firefox has been installed, navigate to the top menu bar "Tools" and select "Options" at the bottom of the list. Once that box opens, you can select "show cookies" and that will produce a list similar to what I have posted below.
Also, you will select the next check box, which is "Exceptions." Type in
www.tractorbynet.com and check on "Allow". You might want to also enter tractorbynet.com, without the leading
www., since that may also be one of the ways the cookies are setting themselves. I do not know.
In any event, this is the way you can help us. We have absolutely the top PHP database adminstrator in the USA. He is looking into these issues. So far, we have not found a single thing that we can say, "ah, there's the problem."
So, make the security adjustments to IE, or install Firefox and perform those actions as I have suggested. If you no longer get logged out, then the problem was due to your browser or its settings. In that case, you can switch to Firefox, or update Windows to the latest Internet Explorer V7.
One fellow noted that after having this problem for some time, he got a new Mac and the problem no longer exists, at least for some days now.
I will repeat that there are myriad settings on each computer, and they are constantly adjusted and changed WITHOUT YOUR KNOWLEDGE by Windows OS, privacy tools, toolbar add-ons, updates and many other things.
You have done almost nothing in the way of analyzing and troubleshooting your own system, e.g. booting into safe mode and seeing if the problem goes away. Deleting system utilities, and so forth.
Your making "guesses" only serves to further muddle the issues, and confuse other users. So please be patient while we continue to look into this issue.
