Update 2/11: the final versions are out. Thank you!
Ah, we are finally able to give out new betas that we hope fix the Rosetta app issues. So if you have used our stuff and had troubles with Rosetta apps not starting up, try the following betas. They will run an optimization process upon installation that fixes the Rosetta issues for us. If you're having troubles after a while again, you can re-run the optimization from the Application Enhancer preference pane.
Anyway:
WindowShade X 4.1b3:
FruitMenu 3.6.2b1:
Let us know how it works for you!
