Image Display Issues on Win XP

[Rob Cozens]

Bill, Jacque, er al:

I have been able to achieve acceptable performance by changing the 
Art Card design so the thumbnails are truly thumbnail imageData that 
hide/show the full-resolution images and the Photo Index Card design 
from buttons to thumbnail images.  I also set alwaysBuffer to false 
for all images...and masked the "jerky" display by adding a visual 
effect to card-to-card navigation.  All images still reside in the 
[88 MB] stack file, but the only time an image is resized is when the 
viewer does it via a "Zoom Bar."

One mystery arose during the redesign:  Under what conditions will 
Rev change the loc of an image when its height and/or width is changed?

This code worked in the old design:

	set the height of image targetImage to x
	set the width of image targetImage to trunc(x*1.5)

with expansion/contraction from the original loc of targetImage.

Now I have to script:

	put the loc of image targetImage into imageLoc
	set the height of image targetImage to x
	set the width of image targetImage to trunc(x*1.5)
	set the loc of image targetImage to imageLoc

or the image moves to a new loc.

What could cause this...on WinXP & MacOSX?
