Using file named sleep.pl containing only "sleep 10;", when I run "wperl sleep.pl" from the command line I get another prompt immediately (as expected). When the same command is run from a cmd file however, the cmd file waits for 10 seconds for wperl to finish before continuing. How do I get wperl in a cmd to return immediately? I am using ActivePerl-5.10.0.1005-MSWin32-x64-290470 on Vista sp2 x64.
