GNU Prolog 1.4.5 (64 bits) Compiled Jul 14 2018, 13:19:42 with x86_64-w64-mingw32-gcc
Windows 10 64 bits version 2004, OS compilation 19041.804, "Windows Experience Pack" 120.2212.551.0, running in a i7-8565U CPU, NVidia GeForce MX150, Intel UHD 620. If I key "F1" or click in the Help->Manual menu, GNU Prolog console closes without further notice. However, if I key Shift+F1 or click Help->Index Search, the Windows help opens in the native Windows application and the manual can be browsed. The binary was installed without changing anything from defaults, except for the association of file extensions .pl, etc. to gprolog. As I could not find any other instance of this bug reported I'm submitting this to your appreciation. Regards, -- Cesar Rabak
