I had the breadcrumbs feature activated on my old computer, and now that I've moved, I cannot enable breadcrumbs in Eclipse. I added the "Toggle Java Editor Breadcrumbs" button to the navigation bar, and the button is simply disabled. Same is true for the "Toggle Mark Occurances" button ...
Anyone know how I can reactivate this?
