My guess is that Alexey didn't notice a dll-in-use-must-reboot warning on
cygncurses-8.dll when running setup.exe, and a reboot might have fixed it.
Erk. I wonder what happens if you update, it adds a file to the
rename-on-reboot list, then update again - this time without a shell (or
whatever) running so that it goes ahead and installs the even-newer version
successfully. I suspect a reboot might bring auto-downgrade in its wake :-(
not good.
Alexey, if this happens, you might need to reinstall libncurses. If you
haven't rebooted yet, is there a file called "wininit.ini" in your \WINDOWS
folder? Or any file matching "*.dll.new" in /bin?
cheers,
