Since I got leopard my bluetooth has occasionally been failing and the icon says bluetooth not available. I have found out that this is not just happening for me but for others as well. The only thing that seams to work to fix it is to shut down my computer and leave it like that for an hour. Does anyone have an idea that may be able to help me out. This is not a hardware problem so please don't give me suggestions that would only pertain to hardware problems.
