End user has Windows 7 Pro 64-bit SP1 with Norton Internet Security 2014 installed. Uses IE11 (Required for the websites he uses) and never had a problem opening his tabs (6 in total) until after installing the Norton toolbar last week to start using the Norton Identity Safe. Immediately following the install IE will open between 3-5 of the tabs, but never all of them. It is random as to which ones will open, but always a minimum of 3. The tabs that don't open will never display anything and cannot actually be clicked on.... Eventually they just disappear. Again, no error messages ever. All Windows updates are installed. If we remove the Norton toolbar, it works properly. Waiting for an update to the toolbar is hopefully not my only option. Note: The user doesn't open all of the tabs when he starts IE, rather he prefers to use the favorites bar and open all in tabs. I have never used that method, nor do I regularly use IE any more, so I am looking for some help.
