Cannot Change Status on Check In

I am having a problem checking a drawing into the vault. Ihave always been able to check in a drawing and select the nextStatus, which in turn increments the revision. Today, I find thatthe Status cannot be changed. If I choose another status from thetop dialog box, the Apply button remains greyed out. I have donenothing with the Vault Admin for a long time, and no one else hasaccess to it.

I asked another user if he had ever seen that behavior, and he saidhis almost always does that, and has for as long as he canremember. His solution is to check-in at the current stats, thencheck-in the identical version again, and it lets him change thestatus then.

Something is wrong there, but I don't know what, or why my computeris suddenly showing this issue. The clients and server are on thesame SP.

Any thoughts?SolidworksWorkgroup Pdm
