slide show screen saver and two monitors

[=CfC=Woof]

To all the dual monitor whiz bang kids in CFC:   Does anyone know how to fix my photo slide show that splits itself between the two monitors?  The major portion appears on the #2 and the remainder spills over onto #1.   I can't do any dragging as as soon as I click on the mouse the slide show disappears.
A miracle solution would be greatly appreciated.
