Since the update, switching to the Radar layer seems to always disable whatever isolines I have turned on. I like to leave the pressure isolines on all the time, and they stay when switching between the other layers, but as soon as I click radar they go away (and don't come back until I manually re-enable them).

Other than that, the new radar layer is great (though like others in this thread, I did kind of like the ghost image of the most recent data).
