To have 4 different Touch Screen Launchers you need to do the following for each of your 4 Touch Launcher Screens (red,blue,green & black):

1) open touch launcher - change all the 9 buttons to launch the programs you want and choose the background color.

2) copy c:\documents and settings\admin\application data\sony corporation\vaio touch launcher\ApplicationData.dat and paste to the same directory. rename it one.dat (do steps 1 & 2 three more times for two,three and four.dat)

3) Put the attached one.bat, two.bat, three.bat, four.bat files into the "c:\documents and settings\admin\application data\sony corporation\vaio touch launcher\" directory

4) make a shortcut on your desktop to each .bat (or use UXBB see this thread)

5) click either one,two,three or four shortcut depending which launcher menu you wish to see and click the Touch Launcher Button OR use one,two,three or four "clicks" of UXBB.

6) This hack is a "switch" for the Touch Launcher should you wish to just click a shortcut to get to that menu straight away then edit each .bat by typing in this at the bottom:
"c:\Program Files\Sony\Vaio Touch Launcher\VTLauncherMain.exe" (include quotes)

Each .bat can be edited by any text editor.

If nervous about running .bat files then save, extract from zip and choose each one and check what is inside.
