My unlock screen on s2u2 will sometimes freeze when the phone wakes... the wallpaper will show up distorted and the slide switch will show up out of position. sliding my finger across every which way won't unlock the screen. the only way i can get it to unlock is to out the stylus out (i have it set that way). Has anyone else had this problem on their touch diamond/pro? I did change the wallpaper from stock to a comparably sized jpg file in the gfx folder,... I wonder if that might anything to do with it?
