I'm running DreamStudio 12.04 LTS on a Toshiba laptop, amongst others. Until shortly, application icons in the desktop Launcher could be easily moved to a different location - but suddenly not anymore. It's only possible to move the whole section up or down a bit - after which, invariably, it jumps back to previous position.
Any suggestions as to how to repair this?
Someone might, but Ubuntu Studio and DreamStudio is not the same thing. Since DreamStudio is using Unity you could try the regular Ubuntu forums since it seems to be more connected to Unity. Or try the http://dream.dickmacinnis.com/forum/ .
