WordPress MU

When attempting to preview a page (not post, that works fine) I get the following error:
"You do not have permission to preview drafts".

Is anyone else experiencing this?

A quick google will always show if anyone else is having a problem:

While this seems to be the solution many folks are pointing people to:

That wouldn't really apply with WPMu unless you;re doing domain mapping or some other trickery with site or blog urls.

I do see this on the wp.com forums and, even though it says posts, this would be the first thing I would try:

I haven't had anyone ask me about this on my own installs. AT least I don;t see any open tickets on the issue.
