How to unlock toolbars in Eclipse 4.2 (Juno)

Question

I migrated from Eclipse Indigo (3.7) to Juno (4.2). In Juno all toolbars seem to be permanently locked. Is there a way to unlock them so they could be moved or rearranged?

Answer 1

For Eclipse Kepler, I have reported the bug again (the fix to the previously listed bug doesn't appear to have made a difference), and listed a workaround.

Changing the CSS for the org.eclipse.platform plugin to use ../images/ instead of ./ in all of the image URLs should cause it to start working.
