You need at least Internet Explorer 10, or you may want to give Firefox or Chrome a try.
Hey kate? how do you change the layer without going over the start picture?
hello sorry about the late reply,
I just make like 4 layers, and don't touch the background one, or I just delete it outright. so I can move a blank layer to the background and draw on that, without going over anything.
hope that helps explain it.
