I see you mention that there is a bug in the statistics area of the random block, which is the block I would like to use. Is there a way to disable the statistics part showing up? I keep putting 'n' in the field in the block administration area, but it never stays 'n.' If I just have to wait, that's okay, but I wasn't sure. (Really tired, so I don't know if I'm describing this well.)
EDIT: I managed to get this to work by going into the database and making the following change.
Looks like there's some problem with the serialization, but this fixed it so the stats (which appear to be broken) won't show up and confuse my poor managers.
