Problem with cropping picture..

[momidadah21]

I'll try my best to explain my prob but this is just minor..

i just want to change my primary photo in my facebook.. i click the picture i want then it will lead me to a page where i need to crop the picture by dragging the corners of the the white square to my desired size and position.. i tried to drag it but it won't move.. if i pinch it, it is the page that is being resized and not the picture..

did anyone encounter this problem too? i hope someone in here can help me.. thanks in advance.. i'm using my GN 10.1 that's why i'm posting it here..:'(
