When I pause all the downloads in JDownloader, and there's a big list of 10+ downloads, a progress bar appears at the bottom which says "Stopping current downloads" that fills really slowly and in fact when it's complete, the application does nothing, it just hangs, the transfer graph doesn't update, and the application never recovers so you can start the downloads again.
Does this happen in other OSes? Does this happen to anyone even in Mac OS X?
