[Newbies] Themes question

[ppadilcdx at gmail.com]

I made some modifications of the themes as discussed on another thread. Since the changes are in the class the running instance didn't seem to see the changes until I ran the class creation/initialization method. Unfortunately that reset all my font sizes selections. Is there a better way to reinitialize a theme after changes without trashing the preferences? Apologies if this should be obvious - newbie to Squeak/Smalltalk.
