surprisingly my bf's satio hang when he changes his standby themes. he downloaded some pics from internet for wallpaper, then when he change the wallpaper and then change the standby themes from the default SE to any other, it will hang, the menu at the bottom of the screen will disappear and will kick u out back to main screen even when u press the menu button. then need to restart phone and change back to the default SE standby themes only can. anyone here experience same problem? could it possible a wallpaper (jpeg file) can cause such issue?

well, to further simplify, it is after change wallpaper, then change from classic menu to any one of the other 4. then the options located at the bottom part of the screen will just disappear, the shortcut keys will be haywired.
