@BoltBait - Windows 10 Pro - Version: 1803. No Desktop customize.
@Rick Brewster - Nope... tried the short-cuts to no avail. The only thing I could do was to kill the app.
I finally reinstalled 4.0.12 and it too appeared that way but I was able to maximize the window.
No idea what caused it. I did try to reinstall over the 4.1.1 but the same thing happens.
Not sure how to describe this one. I installed 4.1.1 (with no errors) and when I run it, all I see is a bar (see attached image) and the minimize, maximize, and close buttons do not work.
