TSQL pane (n)~ One of the tabs that hosts the editor control to allow TSQL code editing. TSR ~ (Terminate and Stay Resident)- A program usually loaded automatically on startup which remains in memory to provide particular functions such as connection to a network or protection against viruses. In Windows TSRs are usually represented by icons in the- System tray such as the small loudspeaker which represents the volume control for the soundcard. A few TSRs are essential but many are installed automatically by a particular application just to improve its own performance with no thought for anything else you may be doing and may have a negative impact on everything else. Sometimes launched from the- StartUp folder- in the Windows- Start Menu but often elsewhere as it is too easy to delete them from there.
