Drag and drop is broken in Unity
I'm testing 12.04 64-bit, with all the latest updates. As far as I kow, there is no way to drag and drop files between:
1. Two maximized windows
2. Two windows from different workspaces
except if target application is registered for file type that is dragged (then, the file can be dragged to application's icon in Launcher). I often need to drag a file from nautilus to k3b or thunderbird that is on another workspace, and this cannot be done in 12.04's unity (if it can, PLEASE say how).
I used to solve this problem in 11.10 by using scale plugin. I could define an action that triggers scale for all windows to some screen corner, and I could drag-and-drop files that way. But, in 12.04 scale plugin cannot display windows from all workspaces anymore (https:/
