Dear Experts,
I am using Acrobat DC on Windows 10 (latest updates of both).
When starting Acrobat DC, the window title and the menubar is visible. But if the window is not maximized, window title and menubar are getting invisible, as soon as the mouse is pointing over the upper Region of the program window.
I have to press F9 to Display the window title. Then if pressing F9 again the menubar is getting visible.
This only happens, when Acrobat DC window is not maximized.
I've found some articles describing a problem with McAfee Virus scanner - but I do use Sophos Antivirus.
Any help is appreciated - this Problem exists since several months now.
