Hi Bertrand,
I think that this issue was mentioned in the Support Section. Same 'Naked Eye' situation that you described. Check out the Visual Support section to see if you're seeing the same thing as was reported there.
Greg C. said that he's away from his computer until Monday, so there's not much that he can do until then.
Hope this helps,
Phil S.
Edit: I just checked in the Support section. Craig L. reported this issue, too.
