Perspective Switching Pane Gone in Eclipse

问题

The little Perspective Switching Pane is gone from the upper right hand corner of my Eclipse Window after an Eclipse crash. I downloaded the newest version and tried opening that (with my same workspace), but the buttons are still gone.

Here is a screenshot:

And zoomed in:

Any ideas?

I can still switch perspectives by selecting Window->Open Perspective

Thanks

It's not just the perspective switcher that's missing, it looks to me; there's no tool bars, ether.

You might check Window..Preferences..General..Appearance, and fiddle around with the Perspective Switcher control, see if that makes a difference.

You could also use Window..Customize Perspective and see if anything looks interesting there.

Try Window > Reset Perspective...

Another possibility is to delete the workbench.xml from [workspace]\.metadata\.plugins\org.eclipse.ui.workbench, which forces the platform to reset the workbench-layout.
