I am clueless here, I've done research, tried to find a program to analyze memory better, etc. and I have got no where. Hopefully someone can help me out here or point me in the right direction. I have 4gb of memory, my activity monitor is showing programs that are using about 1.5gb, yet the graph below says I am using close to 4gb, which makes no sense. How do I find out what is eating my memory? Thanks for your help. Here is a picture of my activity monitor so you can see for yourself.
