Conor,

I was thinking that someone may want an invisible button for things other than
admin control, so I figured it was at least worth answering the original
question, though I agree with JC about Murphy's law.

I'll start with the obvious way, using an actual button. This is handled
differently in the monochrome an color environments. For monochrome, you can
create a custom button that matches the same color as the background. If this is
just in some empty corner of the GUI, it would be an all white image in the
button. You could also use an anchor around any image, which has the effect of
inverting the color polarity when pressed. The image doesn't necessarily have to
look like a button, therefor is hidden.

In the color realm, you use transparent images. This could be a GIF or PNG.
Again using custom buttons with or anchors around transparent images. With color
you have many more options as far as how much indication you want to give that
it was pressed, such as 256 levels of transparency/opacity. You can create some
cool effects with this.

Finally, the Area Map can be used to create a partial anchor inside of any
image. This is a rectangular, hittable region that functions exactly like an
anchor, but you can define exactly what portion of the image you want the
hittable region to cover.

Hope this helps someone.
