I just updated to W10. If I open several files/documents I get the icon in the taskbar (the bar at the bottom of the page), hover over it and see the documents that are open. I then open Chrome and the Chrome icon appears in the taskbar and the documents open icon disappears and all the files seem to have been closed. If I then reopen the files the Chrome icon goes away and is closed without me doing anything. I have a bunch of icons on my taskbar. Could this problem be due to space on the taskbar? Why are my files closing without any input from myself? It seems strange.
