Hitting the Down-Arrow key once or twice, enough to make the window scroll at least once, is enough to get the PageDown key working. But once you're up at the top of the window again, you have to use the Down-Arrow key to get PD to work again. :-/

It looks like they're going to drop the hammer on the GUI changes soon - https://mail.google....l/en/newlook.html

Progress... :-/
