Flashed GV 2.1 straight from GV 1.6. Now I'm having a strange problem. In some apps, when I am moving forward (i.e., not moving backward - hitting a submit button or a link) I'll end up with a black screen. The app isn't frozen, because the back button will get me back and then it usually will work the next time. However, sometimes I can't get back to the launcher afterwards and I end up rebooting the phone. Am I the only one with this problem?
