It used to be when I entered an equation and had it solve it, the output cell was selectable. The cursor was the standard vertical line, and I could copy sections out of it. Lately, I get what looks like a crosshair cursor--a circle with a plus in it. I cannot select any text nor copy it, and if I click on an output cell now, all that happens is the whole cell becomes ''selected''. What in the world did I do to change this ''Output mode'' or whatever happened? How do I get it back to how it used to be?
