Photoshop Elements Brush Size ($10).  Normally I can right click when
using a brush or clone tool and choose the size and shape that I want and
it appears in actual size over the photo.  However, I sometimes lose
control of this feature and no matter what size or shape I pick using
a right mouse click, all I get is a cross hair indicator over the
picture.  I have tried resetting the brushes and tools to their
default values, but I still just get the crosshair indicator.  What do
I have to do to get the brush size and shape to display over the
picture again?

Check that the shift lock (caps lock) is NOT depressed. It is used to
toggle between showing the round brush size on the image and showing a
crosshair which is handy when doing detailed work like filling in
individual pixels around lettering, for example. I'm sure you'll find
this helps!
