Copy and paste problem

[sl60]

I copied one image to be pasted into another image. In the existing image I selected the area where the copied image should go, hit "paste into Selection" and get a blank field the size of the copied image surrounded by marching ants. But no copied imaged image. I cleared any possible remnant selections with "select none" on both images and tried again. Same result.

Any ideas?

Best guess. You are not copying the initial selection.
