in reply to Open a second DOS window

I don't think this is possible. You could maybe try redirecting STDERR to a file, and typeing it from another console window though, using something like...
perl myscript.pl 2>stderr.txt
...though this only works on later Windows versions - 2000 upwards, I believe. For earlier versions, you could try one of the various DOS redirect utilities available.

HTH, Ben.
