Ok, so my guess is that your taking the shots from the film viewer using the print screen button and pasting into paint. This method works, all you have to do is pause the film in the viewer at the time you want to take the shot. Next, press the button that displays the viewer to full screen. After the entire image loads up, press the print screen button (above the insert and delete buttons). This is like doing a copy on your entire screen. Then paste into paint and viola, full screen pictures.
