I have a web-site that runs for external customers on the internet and for internal users on an intranet.
In IE11 with no compatibility mode set the intranet site asks the user to log in for every pop-up page however this is not the case with the internet.
Now if turn on the Compatiblility mode then the intranet and internet work the same in that the users do not need to log on to every pop-up page, however the site formatting in lost when the Compatibility mode is set.
In Chrome,Firefox there is no problem. I think it is something to do with the security and zones but have tried everything.
Any suggestion would be appreciated.
