I never experienced this before but since I decided to hide my taskbar with the show/hide taskbar docklet I have noticed that when I click on the IE icon on the dock it always opens one working instance of IE and another blank page of IE. The blank page stays minimized and I only know it has launched by hovering my cursor over the IE dock icon. I am using IE 11 on Windows 8.1. I do not need reply's about how bad IE and 8.1 are or try another browser. I do use other browsers such as Palemoon but there are times when I prefer IE.
Any ideas or has anyone else experienced this?
