This is not a show stopper because I have learned the work-arounds, but it's highly annoying. I often have 3,4,5 sessions of File Explore open at once. [old habit] I can use the keyboard to copy/paste, etc with no problem. But if I use the right mouse click to "copy" or check Properties, or anything else, file explorer freezes for a few seconds, then closes. In fact it closes all sessions and shows the default Windows screen [as if just booting up] and finally all the icons reappear. It takes about 15 seconds for the screen to return to normal. Replacement mouse does the same. Right click works perfectly inside a file, like to copy text, etc, and inside every other program. Only in File Explorer does it totally crash, no matter if only one open or many. Any ideas or suggestions?
