Acrobat 2017 standalone is installed on a Windows 10 desktop PC. All of a sudden, the top inch of the open window, including the menu, dissappears. We have not been able to figure out why. The computer is using an online content management system called Maximizer and an online tax client software called UltraTax. We also have Office 365 that we are using installed on the desktop.
Does anyone have any ideas what might be causing this to happen? Rebooting the computer fixes it - for a while.
