I found this to disable it all together..
Fortunately, you can automate the disabling and enabling screen saver procedures with a couple of registry shortcuts. Follow these steps:
Launch Notepad and type the following four lines. (Note: The second line must be blank.)
1. Windows Registry Editor Version 5.00
2.
3. [HKEY_CURRENT_USER\Control Panel\Desktop]
4. "ScreenSaveActive"="0"
Save the file to your desktop with the name Disable Screen Saver.reg.
Change the 0 to a 1 in the fourth line.
Save the file to your desktop with the name Enable Screen Saver.reg.
Now, when you need to disable the screen saver, just double-click the Disable Screen Saver.reg shortcut. To enable the screen saver, simply double-click the Enable Screen Saver.reg shortcut.
