1680	initial news layer receiving events	anonymous	framm	"josm official build 1010.
open josm, download any bit of data, zoom out with mousewheel. delete this layer.
notice how new page has scrolled down, thus indicating that it was open all the time & received mouse events.
as for a complete noncoder, this looks to me like this layer is not closed and receives mouse events, which probably loses a few milliseconds every hour ;)
if feasible, this layer should not receive mouse events, or maybe should be just removed when another layers are present (but downloaded content should be cached in case this layer is restored again)."	defect	closed	trivial		Core		worksforme
