Note sure I understand what the bash solution is:
I do startxwin to open an X-session, then I do
bash
and then run
perl myscript.pl
This stumbles on the same problem
So if I understand you correctly, replacing "gracebat"
by "C:\path_to_gracebat.exe\gracebat"(which cmd.exe would presumably understand)
would work?
