How do you "launch" notepad? Code is more helpful than pictures you know.

What's probably going on is that you're using system to open up notepad ... consider these oneliners

perl -e"system('notepad');"
perl -e"exec('notepad');"
perl -e"`notepad`;"

The documentation for system and exec explains things, but I think you want exec.
