I am using DNN 7.0.4 installed by my webhosting provider on their webserver. After logging in as superuser or portal administrator, DNN pops up a new window of the page where I logged in, instead of taking me to the original page. That is, I now have two windows on top of each other, with the original page sitting greyed out in the background. This has never happened on my previous DNN site (7.0), and is extremely frustrating. Any suggestions, please, on how to overcome this.
