Tool and cursors went bad

This happens once a year or so, and I can never remember how to recover. For example . . .

The Select pointer no longer appears on my images when I move the mouse over them. I see the mouse pointer outside PHOTO-PAINT, and above the PHOTO-PAINT  toolbars and menus, but the pointer disappears the moment it SHOULD pass above a bitmap.

The Clone Tool: I use it all the time. Normally, I see TWO circles: One where info is pulled from, and one where that info will go to. Now, I see two little paint brushes, side by side, with no circles to indicate nib size, so I have to guess how large my clone work will be.

I have tried holding SHIFT while launching the application, but this does not work.

Can this be fixed without reinstalling the software?
