The text of the image appears to be unmodified. A simple test so you can see what I see is to get the Mac Classic question icon from the image library and then select it and:
set the text of the selObj to the text of the selObj
You should end up with what appears to be a blank image yet the following put's true:
put the text of the selObj into tText
set the text of the selObj to tText
-- image is now blank
put tText is the text of the selObj
-- true
Any ideas?
