Ok so this happens all the time to me and I cannot figure it out. I know the problem is between the keyboard and the chair but I am working on a picture. Copy and pasting for instance one piece of one into another. Or right now I was cropping the background out of the a picture of my daughters cheer group I want just them not all the other stuff to put into an image for their website. everything is going fine I am probably doing it the wrong way but I know it will work I used the trace tool thingy to draw around them slowly but leaving a some little pieces here and there rather than cut anyones hair or head out and plan to erase it out or cut it or whatever. I am doing fine when suddenly the eraser will not work on the picture as if I am on a wrong layer or something. Only I check and can't find anything but the one layer. This happens a lot sometimes it is with the pen or other tools. When I copy and paste a piece of another image in then place it and let it become part of the picture and it is there and a part of it then when I try to do anything it just doesn' work once again as if I am on the wrong layer. Sometimes Ican save and close and bring it back up and then it works. the "merge" layers is not an available option. I know this is something very simple and I am missing something can someone please tell me what it is? Also any easy way to cut people out of a picture my way takes a while.....Thanks in advance
