Ok, update from Keith, You aren't supposed to run the think 1.21b with 1.21c server

, however once each job finishes you'll have to stop each process, Then when they are all stopped, reset all jobs showing green in the queue (status 5) then shut down the server, replace server.exe, replace think.exe, delete clients.dat, then start them all back up and you are rolling, and it will tell you when a job is stalled on any client (just not which one) it now refreshes every 5 minutes or less.
Problem he said, tho I didn't run into it was queue server unlock issues. I'm now running 1.21c for both, very nice little changes.
Or, you can forget all of this and just let update do it after 11:30 GMT (should be now) hit the recieve button and it will do all that for you.
