Since clicking the button gives you both X and Y co-ordinates, and not clicking it
gives you neither, why even bother checking both? Just testing one or the other would
be quite sufficient. (And, if you insist on testing both, it makes no difference
whether you use and or or -- just so long as you don't use xor!)
