If you upgraded to Ubuntu 11.04 (or installed a fresh Natty Narwhal system) and are running the Classic desktop, you may find something amiss with the ability to bring folder windows or programs to the foreground by holding an item over its taskbar button until it appears.
For example, you’re looking in a folder at a sound file you downloaded, and wish to play it in Banshee, which is already open but hidden from view. Normally, you would drag the file over the Banshee taskbar button in the bottom panel, wait till Banshee appears, then drop the file onto it.
A more common use is perhaps file management, when you’re dragging files and folders from one Nautilus window to another which is hidden from view. This is most handy, as it means you don’t need to carefully line up both source and destination folders before doing the drag-and-dropping.
But you may find something is preventing you from doing this, with the only thing happening is a + sign appearing, and if you finally let go on the panel instead of press the Esc key, a launcher will be created there, which you then have to remove. This is not some new setting you can change in Nautilus‘s preferences (which is evident if you try with another file manager like Thunar), but a Compiz bug. While that obviously needs to be ironed out, there is a way around this, which is to run the following command in a terminal:
Note that the next time you restart, things will be back as before, but at least you can just run that command again (which you can easily do by hitting the up arrow when in the terminal, or pick from the menu in the Run dialogue via Alt+F2).
Also note that if you try adding that command to your startup programs, it will likely do nothing, but you can always make a launcher for your panel, which you can then click once everything has loaded, or when you go to drag stuff via the taskbar and remember you need to.
This bug will likely be fixed soon enough, but at least there is a way around it for now.
