For future referrence another way to select things (and it is especially good to give each thing a meaningful name) is to click on the icon at the bottom of the screen and select it from the drop down list. 
For instance if you had five spheres and named them posSphere and negSphere and ball etc
Then you can just go to the drop down select posSphere and hold the shift key and select negSphere. It can save time and agony , especially if other objects are blocking the object you want to select. Takes out the guess work.
I also like to take selected objects into solo mode to make tweaks and adjustments to them.

HTH :)
