View arrangement: Drop border colors and cursors [message #1410686]

When I arrange views in my Eclipse IDE (Juno SR2) I see green outlines that give a hint on the future placement.
In my own RCP application (RCP 4.3.0, no explicit E4 use) this outline appears grey and is hard to see if at all.
Is it possible to explicitly set the color or at least get the regular green color? I fail to find relevant links in the internet, possibly because I miss the correct term for it (Eclipse bugs refer to "drop rectangle", the manual says "rectangular highlight").

Also the online help for my IDE describes drop cursors in the same situation (Workbench User Guide > Tasks > Working with views and editors or http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.platform.doc.user%2FgettingStarted%2Fqs-39c.htm).
The drop cursors described there do not appear in my system (Windows 7) neither in the original IDE nor in my own RCP application. The only cursor from the table I have is the restricted one. All others appear as a simple "Hand" symbol not included in the table.
Any idea how to fix this?

The drag outlines are configured through CSS via the "DragFeedback" and "ModifiedDragFeedback" classes. In 4.3 the CSS files were part of the org.eclipse.platform bundle, and in 4.4 they were separated out into an org.eclipse.ui.themes bundle.

Thanks a lot for the quick reply. It works for me.

In case others have the same problem:
My RCP doesn't explicitly use E4 functions. The CSS can however be easily added using the org.eclipse.core.runtime.products extension point.

Add a property to the product named "applicationCSS". The value must point to the CSS file so something like "platform:/plugin/<name of plugin containing the CSS file>/default.css

The file now contains:
.DragFeedback {
background-color: #00FF00;
}

During migration to RCP 4.6.2 I have problems that the applicationCSS property in the org.eclipse.core.runtime.products extension point is automatically removed by my Eclipse IDE without any notice. If I add it again the definitions in the CSS take no effect. The IDE will later again try to remove the property without notice.

Any ideas how to color the drag borders without fully migrating to E4?
