RMA processing in 5.1

We are trying to process a RMA from a job return. We have reopened the
sales order and attempted to add the line in RMA processing but it just sits
there when you click OK after adding info to it. Any ideas? It was a build
to order job and the job is closed.

Thanks,
Darren Mann
