With build 3170 and 3186 I can quit it quicker than it used to, not very long looking at the hour glass. When I reopen and press the play button I get a few seconds of the resuming message and then see the desktop exactly as I left it (including any icons highlighted that were when I quit). Unfortunately nothing operates. Trying to select icons, or deselect any that were selected when I had quit, doesn't do anything. I have to click the Reset button (or the Stop followed by Play) for it to recover.
