I just updated my MacBook Pro 13 inch mid 2012 model to OS X Yosemite, and the icons on my desktop are behaving strangely. When I try to move a file or folder to a specific place to keep my desktop organized, it doesn't let me put them where I want them to go.
Below is a screenshot of my desktop. I tried to move the folder with the red 1 on it into the empty space where the 2 is, but it wouldn't let me, and the folder moved back to where it was. However, if i were to move the folder to the number 3, it would let me do this.
