Comment 6 for bug 870769

Specific steps to replicate:

1. Open Nautilus and Gedit.
2. (For comparison): Shrink Nautilus so the editing surface of Gedit is visible. Drag a text file from Nautilus onto the editing surface of Gedit, and release it. The file is opened.
3. Drag the same file. The launcher appears. Move the mouse over the illuminated Gedit icon, and hold it there without releasing.

Expected result: The Gedit window is focused, so that the file can be dropped onto it.
Actual result: The Nautilus window retains the focus.

Obviously for simply opening a file, you can just release it on the launcher icon to tell that application to open it. But there are cases where you want to drag a file to a specific part of a window. E.g. GMail in Firefox supports dragging & dropping files to attach them when composing a message, but this is distinct from opening a file in Firefox.
