hey
since i updated maemo a week ago my browser reloads sites like youtube or kino.to without me wanting it...
every site with videos in it... facebook and other normal html sites work perfect...
it lets me watch between 1 second and 1 minute of the video and then randomly reloads the whole page so the video starts over again...
dont know how to describe my problem any better because of my bad english but does anybody know whats wrong with it?
can i reinstall micro-b without reflashing the whole device?
thanks
waaah
