Every time I start up Eclipse (Juno SR2), it reverts to the Java EE perspective, regardless of what perspective I was using before. When I add and switch back the the Java perspective, it has also reset all my windows (Search, JUnit etc.), and all my opened files has been closed as well.
We are a few people here who experience the same problems. Does anyone know how to prevent it?
Try setting up your perspective and configure it as you want it, and then select Window > Save Perspective As... Give the perspective a name and press OK.
Then go to Window > Preferences > General > Perspectives
Find your newly saved perspective in the list, select it and then press Make Default.
