Eclipse Juno GUI (Theme)

1.
To change to older theme:

General --> Appearance --> Theme: Classic.

2.
Also, I found in this blog that it can be changed at lower level:


plugins\org.eclipse.platform_4.2.0.v201206081400\css

to something like,
plugins\org.eclipse.platform_4.2.0.v201206081400\css.old
