If you're talking about the abort button on the tool bar, this should always be disabled or the toolbar hidden. Either can be done from VI Properties>Window Appearance>Customize. If you're talking about a stop button on your VI that terminates the main while loop in your VI, my limited experience with remote panels indicates that when the main VI stops, the run button on the toolbar becomes visible once a client is granted control and the VI can be restarted just by clicking the run button. If you don't want the client to have to restart the VI, then you should change your program so that the stop button does not terminate the main while loop. Also, if your VI calls the Quit LabVIEW function, remove that function.
