 The LOADUPDATE option reloads the script file and updates the panel. This
 is usefull if you make use of env variables. If selector was loaded
 with arguments, these will remain the same. If the window parameters
 (size, title etc.) not are changed, then the window don't have to be
 closed and opened again, and this speeds things upp a lot. It also
 prevents you from "jumping" to the workbench every time the window
 is updated. So if you like a fast update, then make sure that the
 window size is the same. You can do this with the size command.
 NOTE: The X and Y parameters will be ignored on an update. The new window
 will remain in the same position on the screen. If you want X and Y not
 to be ignored, please use the LOAD [this] option instead.

 The UPDATE option works in the same way as the
 LOADUPDATE option, except that the script file not is reloaded.
 
 The LOAD <filename> [arguments] option is similar to the LOADUPDATE option.
 But LOAD loads the script <filename> and rebuildes the panel after
 that file. The possibility of passing aguments with the load command was
 introduced in Selector 4.1
