The best way to use Adkreator is to open it in a New Private Window using Firefox web browser. Just right click on the Firefox Icon and click on “New Private Window” with the purple mask icon on the drop down menu. Doing this will solve all of your freezing problems when working on editing and/or building your pages and banners. But I still highly suggest clearing your cache and deleting your Adkreator cookies as well. See the FAQ’s 1st one and 7th one down for directions.
Have a great day/evening!
