I have schedulled Task Manager to show a ppt presentation at logon time. But
instead of starting the show it opens the .ppsx file for editing.

On my first try I filled the field "Action/Start a Program/" with the path
of the .ppsx file.
On the second try I filled the field "Action/Start a Program/" with the path
of PowerPoint and the field "Add an Argument" with the path of the .ppsx file.

Both failed. I'm using Vista Ultimate (64bit) with Office 2007.

Thanks for any clues,

Peter
