Thumbnails in Preview

[Bill Raffensperger]

Here's a weird one. I have found sometimes the thumbnail  in the drawer 
in Preview has a slightly different picture than the jpeg in the main 
window. I am using Preview 2.1.0 (v210) on an iBook 600, with Mac OS X 
10.3.2. Under Images in the Preview Preferences, I have selected: 
Default image scale - Actual Size and I have checked Respect image DPI 
for "Actual Size".  The thumbnail is the jpeg before it was cropped and 
resized. Under Preview Preferences - General, if the thumbnail size 
slider is pushed over to max and released, the glitch disappears and 
the thumbnail matches the window image. It's like the jpeg file 
contains some history, and the Preview action that creates the 
thumbnail somehow reads the old information. It only seems to happen 
with images that came from a PC, not Mac images. Anyone else seen this?
