>I do not know if this is related but here is how this problem started. A few weeks ago, I discovered that, after a while, lets say 25 minutes to an hour, if I am logged to the site and open a new browser window (right click on top of the Internet Explorer item in the taskbar and select Internet Explorer), that it creates a disconnection to the site. The cause is because it erases the cookie in the browser. If I keep logged in the Universal Thread and do not open a new window, no matter from which instance of the browser opened, it does not delete the cookie. However, if I do the same operation right after the login or before about 25 minutes to an hour, I do not have the problem. This started to be like that a few weeks ago and I have not been able to find what is causing this.

>Since then, testing the same with another browser did not create the same issue for me. So, there is something that is being kicked in when the request to open a new window in IE happens. This is still in effect with or without the secure site. This is not related. This is a known situation right now. I am still trying to find some information on why the browser is reacting like that.

This is not what you asked, but another data point (using FF30).

1. Logged in this morning to UT, lock icon. Browsed some messages. Did NOT log out of UT
2. Navigated to other pages on 1st tab, also opened other tabs
3. Two hours later - closed all tabs except 1st one
4. Used back button to navigate back to most recent UT page
5. Now have warning/triangle icon

Maybe an SSL session is timing out?
