I watched a stream with Edge browser. It worked fine for around 3 hours, then it started stuttering. Then it crashed. But the worst part was, while Edge crashed, it still stayed on the screen. I tried the close button, which worked and put up the question about closing multiple tabs, but then it still stayed on the screen and menu became totally unresponsive. The page that was loaded (sans video) still worked. I was finally able to close it with Task Manager.
I guess I'm just used to when a program crashes or you choose to close it, it actually closes.
