tips on refreshing images in fields?

[rodney tamblyn]

If you've set an image in a field (using imagesource) are there any 
tips on ways to make the images refresh and display properly when the 
field is scrolled up and down (I tend to find after scrolling that the 
images do not display correctly until the screen is redrawn by force, 
eg change tool, lock screen etc)
