When you enable "Autoscroll to Source" in the Project view, the file will be automatically opened/selected in the editor view when it gets selected in the Project view. This works fine, except in the situation where the Project view becomes visible. In this situation, there will be an autoscroll to the selected file in the Project view, which is not wanted. For instance, follow these steps: 1. Enable the "Autoscroll to Source" feature 2. Select a normal Java file -> it is opened in the editor view 3. Select a UI Designer form -> it is opened in the editor view. Because it's a UI form, the UI designer is opened and the Project View becomes hidden. 4. Select the tab in the editor view containing the Java file opened in step 2. You would expect that the editor for this Java file will be displayed. However, because a Java file gets selected, the Project browser will become visible and will autoscroll again to the selected file, which is the UI Designer form which was selected in step 3.
