Believe it or not, but nowhere in the readme or any other file did I see such simple instructions. And I couldn't figure out why sometimes when I would open a window it would work and the other times no nubs.

This just goes to show how even a simple proggie can be frustrating if you don't include (good) instructions for use, no matter how simple or straight forward it may seem to you (the developer).
Thanks for the info Zubaz.
Happy Nubbing to all, and to all a good night!
