Bug 325791 [Compatibility] Closing an inactive perspective closes dirty parts without prompting
Reported: 2010-09-20 15:53:55 | Status: verified fixed

1. Open a file. 2. Make changes to it. 3. Drag the editor outside to a view's stack. 4. Switch perspectives. 5. Close the perspective you were previously in using the perspective switcher. 6. It closes _without_ prompting you about your changes.
