My XOOM WiFi seems to be inresponsive as the launcher will basically crash since there are no longer the soft buttons on the screen when the Xoom has been on for a atleast 4 hours. It didn't have this problem before, I am using the stock launcher and Android 3.2 had the same problem so I upgraded to 3.2.1 and the problem still exists, I had tried clearing data for the launcher and it didn't make a difference. Does anyone know a fix for this?
