There are 3 Win32 system() or open() bugs, all have to do with claims Win32 Perl is not acting like Unix Perl system/open. https://rt.perl.org/rt3/Ticket/Display.html?id=92220 https://rt.perl.org/rt3/Ticket/Display.html?id=54028 https://rt.perl.org/rt3/Ticket/Display.html?id=43631 I can't figure out how to organize them/"Link" them together, or is a meta bug needed for launching processes from Win32 perl?
