Didn't work
I made it so if the first pixel of a costume is a very exact number, it checks out. And it works!

Not possible without using javascript.
Try setting the layers of each clone based on which one was clicked/created last. Maybe? I don't know.

Yeah. Try that.
It kind of sorta worked. I think I'll just leave that bug be. It's not a very big bug anyways.

A lot of people like to call it a Window Management System. Anyways, how do you like it?
I like it, but you should add a taskbar.
I will. Eventualy.
