Object names that you can reference in text versions of scripts do not match object names displayed when you change the object's name.

Drag out two text objects onto the screen. Create a script on the first text object to set its characters to the 2nd text objects characters (textual version of script below)
script1
self setCharacters: Text1 getCharacters

Then if you change the name of Text1, the name in the textual version of the script does not change. Note tried the same thing in Squeak 4.2 and the name did change.

Same problem occurs when you have text on multiple pages in a book. in each page you can have an object that shows the name Text, but in the textual version of the scripts it refers to a different name (ie: Text3)
