About once a week when I press Home from an application, my Droid's desktop is clear. The wallpaper is there, I can page left and right to different, empty desktops, and I can open the application list and run things. The phone isn't locked up but the desktop is empty and remains so until I power cycle. Has anyone else seen this? This will, presumably, require a f/w upgrade. When I first got my phone it checked in, found an upgrade, and installed it. Is that always an automatic process (as it seems to be for applications) or might there be upgrades out there I haven't installed?
