Unable to retrieve old Working Copy revisions

An example in 2007:

Create an inital revision at, let's sayREL
Create a Working Copy rev atREL+
Create another primary revision at001

We're no longer able to retrieve the Working Copy (REL+) rev fromthe vault, even though it still exists in the vault structure (inWindows Explorer). If we check out theREL revision, it is in fact the originalREL revision (like it should be), not theREL+. I could be wrong, but I could swear that this waspossible in 2006. We have not altered any vault settings since theupgrade. Are we missing something that could make this optionavailable?

Thanks
