Friends, esp Tamar,
I am in happy possession of a new Surface Book, running Windows 10, which is delightful - except that I can't make the msys64 installation work, which is crucial for GHC. Can any of you help?
* I install it from here: https://sourceforge.net/p/msys2/wiki/MSYS2%20installation/, which seems to be the canonical place. The actual 64-bit exe seems to be msys2-x86_64-20160205.exe.
* Installation goes fine
* But when I launch the "MinGW-w54 Win64 shell" from the Start menu, the screen flashes as if it is briefly putting up a window, but then the window disappears.
* Each time I do this the task manager shows that there is another running 'mintty.exe'. But it has no visible window
Does anyone have any idea what I can do or how I can investigate? I can't do any GHC development without this!
