The Open Slide Show File window appears when you:
1. Click the Open button on the Slide Show Accessory Main Menu window; or
2. Click the Open item on the File menu on Slide Show Accessory Main Menu window.
The Open Slide Show File window is a file selector. It shows you all the slide show files in your current directory. (You probably created these files by capturing them in PC Access.) You may pick one of these files by clicking on it with the mouse.
