Big White Space on the Screen

[Thomas Cole]

I have a stack that prints a field. It prints fine in the windows standalone and the OSX standalone, but in Mac OS 9 an image of the field being printed appears across the screen and won't go away. It prints, but the user's machine has this big, white mess there. How can I keep it from doing that? It does it with the PPC, OS68,and OSfat standalones. What gives?
Thanks,
Tom
