nice upgrade,but

As Pee Wee Herman once said,"Everybody has a big but"
the upgrade is very nice and easily switches from algebraic to RPN, although I had to figure out how.
my big but is that after the upgrade my icon constantly says "waiting" i can only access the app by "open" command from the app update page
