Menu bar and part of tool bar missing from top of screen.
The menu bar and top portion of the tool bar will not display on Acrobat DC. When I try to click in that area it activates whatever application is running behind the Acrobat window. The only way to close Acrobat is to close the window via the Windows taskbar at the bottom of the screen. The partial icons that are visible will function but I can't access any tools or menu items above that point.
I have tried to uninstall then reinstall the program and that did not help. I have also run a repair on the program which did not work either. This version is installed from Creative Cloud. help please.
