After a week of this glitch behavior, Windows Explorer spontaneously started opening in a window taking up about half the screen and still does so.
Using a hard close with CTRL key and the Close command does not work. I think something in the Registry is corrupted. I run Registry Mechanic every day but it hasn't helped. Is there a way to edit the Registry to get the settings to be freshly rewritten or use Administrative Tools to solve this problem??
Thanks,
