Problem with Lilypond on Intel Mac OS X 10.5.1

[Nick Didkovsky]

Hello

I just downloaded and installed Lilypond 2.10.33 for Intel Mac OS X 10.5.1
Problem: I get no no File, Edit, Compile, Font, Window, or Help menus

Double clicking on the Lilypond icon results in Lilypond opening up with 
the familiar "Welcome to Lilypond" text document displayed.
However, I see only the Lilypond menu, but no menu items (like About 
Lilypond, Services, etc) open up when I click on it.
There are no File, Edit, Compile, Font, Window, or Help menus

Any illumination appreciated. 

Thank-you
Nick
