Execute the script editor by double clicking on a script in the explorer then create the new script (room 2), rather than clicking on the "Script" editor icon on the main toolbar then creating the new script.
SS 3.00-3.01 treats the Script editor executed by clicking on the "Script" editor icon on the main toolbar as a stand alone editor for lose files, where as the Script Editor executed from within the explorer is an editor for the game's scripts.
