x-plane 10 just updated through the program prompt itself. After starting the new version 10.50 64-bit update, none of the cursor accessed menus can be used. The cursor disappears as soon as it is moved up to the menu headings and will not stay until any of the dropdowns can be accessed. I cannot control the program. I cannot even go to File Quit and stop the program. Pausing does not help. The system is running one 4k resolution screen for the main display and a 1080 screen for Panel Builder. Stopping Panel Builder does not help. X-plane 10 is now not useable.
