When I launch the Unity dash in Ubuntu 11.10, any screenlets or open windows on the desktop display in front of the dash instead of being hidden. I have a Toshiba NB305-N410BL netbook, 1.66GHz Intel Atom processor, 2GB of RAM, 250GB HDD and Intel GMA 3150 graphics. Any help will be greatly appreciated. Thanks

That's a bug. It should have been fixed, but it still happens sometimes. It may have to do with applications/windows being exited unexpectedly. Let's hope it gets fixed in Unity 4.26. It should've been released already, but some issues were discovered that forced them to push it back. We file bugs on Launchpad.net, which is designed for just that. This site is designed for questions and answers, and not for bug reports.
In the meantime, you can fix the issue by pressing alt+ctrl+F1, logging in with your username and password, and running the command
If it happens often, and you want to simplify the proces of restarting Unity, then you can add the command to an empty text file, in GEdit, for instance. Make the file executable by right-clicking it, selecting properties and then permissions. From now on, you can just double-click that file to restart Unity.
I realize it's not really a solution, but I think it's the best I can do. Hope it helps. :)
