I get an error, i'll tell you what's wrong in that when i run Squeak. Has it been tested with 3.9?
I experienced the same problem, but was able to run DrGeoII in a fresh Squeak 3.8. Seemingly in Squeak 3.9 two icons for the menu bar got lost (MenuIcons>>undoIcon, MenuIcons>>redoIcon)
Hope this helps Boris
