Noob here. I'm running CM7 from and SD card and it was humming along great for a while. Now, for some reason, I can't do anything with the icons on the home page. Essentially the home page isn't recognizing any sort of long-press. I can't move, delete, or add any widges/shortcuts. Everything else seems to work fine...but that's pretty annoying. Is there a setting that got changed somehow? TIA.
