Here is a strange one. I noticed a few morphs changing appearance after 
saving the image. It seems to be related to the hibernation of Forms 
which happens prior to saving the image. This snippet

(m := SimpleButtonMorph new)
     label: 'Black on yellow';
     color: Color yellow.
Form allInstancesDo: [ :f | f hibernate].    "this happens when saving 
image"
m imageForm asMorph openInWorld

has a white background for the text with a bit of yellow surrounding it. 
Running it in a clean 5.1 image gets the expected result: black text on 
a yellow background. However, if I load the preferences from my current 
image into the clean image, then the problem occurs: black on white on 
yellow. My prefs are attached if you would like to take a stab at it 
(and if it isn't too large an attachment).
