Some very weird things happening to my DX: icons for some apps started changing randomly (apps seemed to work fine), back-arrow hard key not working right on some apps, random reboots, Pandora starts playing automagically after taking DX out of CarDock, etc. So ... today I was downloading some music via doubleTwist (USB), then Windoze Explorer crashed during download and I can't see the DX on my Windoze PC when it comes back up. Somewhere in there I activated the text-to-speech using Settings. I tried to get back into Settings to deactivate text-to-speech, and now I can't get to the Settings - the unit just highlights the Settings box & sits there. Tried to power down - same thing! Have to pull the battery to power off, but nothing is fixed on power-up! I can start most apps okay if they're on the desktop, but trying to start any others is NOT working. Ready to take a hammer to this thing. Any help is GREATLY appreciated!
