Big White Area Appears on the Screen in Mac OS9 when Printing a Field

[Thomas Cole]

My Mac OS9 standalone (created with OSX Revolution) doesn't print correctly. I use the print command in a button to print a field -- just the regular revprint field command -- and a big honkin' white image of the page being printed appears on the screen and STAYS there blocking out the view of the desktop and anything else in its way. I really need to get this fixed.  
Thanks very much for helping me.
