So I've been away from cartography for over a month now (*sheds a small tear*), but I'm coming back. Working on some things on GIMP and apparently I've brain dumped any GIMP-fu I may have once possessed. Now I can't remember how to do a very simple little thing.

Situation:
On my foreground layer, I wanted to apply some effects to all of the drawing on the layer. I right-clicked on the layer (in the layer dialogue) and clicked 'Alpha to Selection'. I then did what I wanted to do with it. So far, so good.

Now, I want to go back and continue drawing on that layer. BUT I can't, because I can't get rid of the marching ants. So I can't do anything.

Question:
HOW do I turn off those darn ants to get back to what I'm doing?

[Any help is greatly appreciated...] (*Extreme shame and embarassment*)
