It would be nice if there was a way to force the TS Client to do a server reconnect (when the TSS has been restarted) - today you have to wait until the client tries to connect as it does every X seconds. There is an Online/Offline indicator in the lower left corner - maybe it could reconnect if you click on that (or right-click > Reconnect).
If Yahoo, Gmail and most Microsoft products can enforce auto server save. why can't Tibco Spotfire?
