I have also noticed somthing like this, when I have the clock on, the display will flick off then on it is very fast maybe half a sec. but it only does this when I have the clock displayed. So far it has not crashed or rebooted but the display will flick maybe every 10 sec. or so. Oh also Im running b13 hijack 289 I know I know hijack is up to 300 now, Im just lazy.
