When I click on the selection tool it will only show as a tool to subtract sections. I have tried to use it as if the whole picture is selected, but it will not switch from the "-".

Question

On top of this every time I open Photoshop this afternoon, the program freezes. I currently can not get the program closed without shutting down my laptop.  I can't even minimize it on my screen. 

Answer 1

I just discovered a fix from a couple of years ago on Apple Support:
In may case the network was already at the top of the preferred networks list.
Based of of a hint over at MacOSXhints.com, here's how I fixed this problem:
1. In the Network references pane, delete the Airport connection that does not like to reconnect.
2. Click Apply and Quit the System Prefs app.
3. Put the computer to sleep.
4. Wake the computer.
5. Go back in to the Network pref pane and re-add the Airport connection. Do not try to connect to the network at this time.
6. Click Apply and Quit the System Prefs app.
7. Use the Airport menubar app to connect to your network.
8. Verify connectivity
9. Put the computer to sleep.
10. Wake the computer.
11. Verify connectivity
