Not really a Java question, but this seems to be the best place for it at ExEx
I am reading the Eclipse RCP book and following along with the Hyperbola example. Somehow the Hyperbola perspective is corrupted (null expection when try to bring it up) so I want to delete it. Yet, when I go to General -> Perspectives -> Hyperbola Perspective, I am unable to delete because then Delete button is greyed out.
So then I tried removing the files:
from the plugin directory and started eclipse with -clean.
Still, the hyperbola plugin appears in the plugin perspective.
How do i delete the perspective?
