Thank you all for chiming in.
I have left it off and the problems seemed to have gone away -for now, I'm sure....
On the other hand, does anyone know what is the purpose/intent of the 2D acceleration selection if almost none are using it or see improvement in speed -except Ben perhaps.
Is it a good intent, not quite delivering?
