What type of Mac are you using and what OS do you use?
Do you have any other machines networked to this machine or do you have another mac?
Your qriginal question was cut off slightly so could you tell us what happens to bring up the wheel?
Let us know
What name did you ask your original question as so I can reference it?
If this did not work to solve your problem, it is just the speed of your processor or the amout of RAM in your system. You could try to upgrade your current system, but you would probably be better off saving that cash and purchasing a new Mac.
