When I select KDE Desktop from the LMCE main screen, I can sometimes get back to LMCE, but sometimes I can't. The KDE screen has the six windows at the bottom. If I stay only a short while in KDE, I can return to MCE by clicking on window #5. If I work for ten minutes or so, then it seems MCE goes away. Clicking on window #5 brings back the Flickr pics but no MCE interface. I go back to window #1 and try to shutdown, but then I get the Kubuntu loading bar like I'm starting up. The bar gets almost to the right side then hangs. I end up having to push and hold the power button. I hate to abuse such fine software in this way. What is the more graceful solution?
