Tim, Thanks for the information. I had tried A and C, but not B and E. D does not apply in this case, but the information is good to have anyway. I have added all that information to my notes. I think that my previous troubleshooting efforts were on the wrong track, and that I ended up making the issue worse, so I elected the remove and reinstall all the SAS components, just to get back to a clean slate. The SAS tab is now back and everything seems to be running fine. If the problem returns, like it did before, I will have more of an idea of what to look at, and will definitely try all the things that you mention before doing anything else. For now, we can consider this one closed. I'd like to thank everyone who contributed information to this discussion. I have learned a lot! --Tom
