I use win 7 and IE 11.0.9600.19080 (edge). After I use IE and close it I cannot relaunch it from the icons on my desktop and taskbar. The IE window appears with the timer icon, which never finishes. Clicking on it provides the nastygram in the IE titlebar "not responding". I have to restart win 7. The usual method of restarting does not work via the start button in the lower left corner. Here I also get a never ending timer icon. I have installed separate icons to shutdown and restart my PC. But this MO is annoyingly inconvenient.
