In my efforts to learn PERL, and presently restricted to a windows environment (Though I recently installed Cygwin to improve my mental state of being) I tend to like cleaning up my output window to see the newest output, making the screen uncluttered. To do this, I use the command  system 'cls' But then when I was running / testing my code, my editor kept giving priority to other windows. IE: I hit F9, and my IE window would pop up in front of my editor. It was most challenging to my normal good mood.

My discovery is this: Windows, my editor, and system 'cls' don't like each other. The moment I removed the call from my script, my output started showing up in my output window of my editor and I was no longer having my active window move to the back of all the other windows.

Granted, I am on windows... I apologize - but for those of you having any similar issues, that was my discovery for the day.

I hope this helps someone
