Sorry for the delay in wrapping this up. The computer suddenly decided that everything was "OK" for no apparent reason and the red bar disappeared all by itself. I guess everything is alright until the next time.
This evening, my m15 R3 told me that I needed to do yet another AWCC update. Once I did that, I got a red "Restart Required" box in the menu bar. I pressed the box, restarted the m15 R3 (more than once) and the obnoxious red box refuses to go away. AWCC seems to be working just fine. Does anyone know how to get rid of this, short of uninstalling and reinstalling AWCC? It's more of an annoyance than anything. But I just don't understand why Dell can't get these simple things right?
