I seem to have an issue with an autorefreshign image on a webpage. The N800 seems to disable the screen, although stays lit, after the set time in the display settings even though it is set to never dim when charging. It seems it disables although doesn't dim. If I change the time in the settings it seems to freeze accordingly.

Is there anyway to override these settings with some utility or somethgi nso it is always on or extended to 24 hours or something?
