Using the image from 
ftp://st.cs.uiuc.edu/pub/Smalltalk/Squeak/3.9/Squeak3.9a-6548.zip, when I try to 
click on active text (blue "hyperlinks"9 in the "Welcome to..." window, I get a 
notifier saying:

"Text>>rangeOf:startingAt:forStyle: has been deprecated. Use 
Text>>rangeOf:startingAt: instead."

NewParagraph>>clickAt:for:controller: seems to be the only sender, and the 
attached change set does what the notifier proposes.
