I upgraded to Windows 11 on a new machine a few days ago. Had to re-install all my software from scratch. I just discovered I can’t create subfolders. Not sure long the problem has existed (I don’t create subfolders very often). I tried creating a subfolder on several different top level folders, on multiple accounts (Hotmail & Gmail). The "name new folder" dialog never appeared. No error message appeared, either. Windows Task Manager shows 2% CPU usage, and 21% memory in use. Firefox Any suggestions would be appreciated.
