White Dot @ Origin - what is it?

See this:

See the little white dot at the origin? I can't figure out what itis. It's not there on new parts, but seems to appear (and stay)after I insert the first sketch. It's always at the part origin,and I can't get rid of it.

It also seems to show up in assemblies, although I don't know whattriggers it there.

Any ideas? I'm on 2007 SP1.1; Dell Precision 390 w/ NVidia QuadroNVS 285.

Thanks,
