Problem moving selected rectangle area

[pstein]

I am confused. After a while of not using Gimp I need to do something which worked the past worked...somehow.

1. I dragged a new image to Gimp
2. I selected "Rectangle Select Tool" and selected an area in the currently visible image
3. I selected the "Move Tool"
4. I clicked into the rectangle area and dragged it.

Surprisingly not the rectangle area is moved but the underlying whole picture.
Whats wrong?
How can I move selected are only?

The Move tool doesn't use the selection. Normally you have to copy/paste or cut/paste you selection, that create a new "Floating selection" layer, that you can move around before you "anchor" it back (Ctrl-H).

There is however a shortcut in the rectangle selection tool: you can depress Alt-Control and drag, this is equivalent to cut/paste plus entering the Move tool. You still have to "anchor" at the end.
