Global Code Style on 7.0.3 EAP

I was looking for a specific ActionScript code formatting style and noticed that when I uncheck "Use same settings for all file types" in the "Global Code Style" preferences - the vertical tabs are somewhat messy on OS-X 10.5.2. Clicking the down arrow I can navigate to a fourth entry tab (besides Java, JSP, XML) which is not labelled/visualized. Using the Quaqua look and feel the tabs are completely unreadable ("...").

Thanks,
Peter
