I have waited for a while before posting this because I wasn't sure. But, now I am. This is not the first time it has happened and happens on a regular basis. As many of us, I leave my PC with a bunch of windows opened and sometimes, during the day and when I come back, I see that one or many instances of IE 10 have closed by themselves. This is new to IE 10. I now that version has suffered a lot from various negative effects and I sure hope an update will be released soon. Am I the only one who noticed that?
