Hi All, Windows 10 Pro
raku -v This is Rakudo version 2020.05.1 built on MoarVM version 2020.05 implementing Raku 6.d. I had a weird symptom calling Raku from Cobian Backup. A black box popped up, delayed about two seconds, then died. The only writing was the flashing cursor. Running the program directly from a shell showed that I had a directory in "lib" that did not exist on the customer's machine: use lib 'K:/NtUtil', 'C:/NtUtil', '.'; Edited out the missing directory and happy camping returned. use lib 'C:/NtUtil', '.'; I thought for a moment that Raku could not be called from Cobian. Had one of those "ah poop" moments -T 'K:/NtUtil' is the network drive I program my various Windows virtual machines from. Since the shell I use is in that directory, "." will suffice.
