[Gimp-user] Crop

[Shantyman <forums gimpusers com>]

After setting the crop tool to 6in X 4in including aspect the values alter as I
crop the image and it is taking further steps to achieve a postcard size with a
reduced resolution. How do I lock the crop dimensions ?
Coming from Elements 14 I like being able to devote most of the screen to the
image and not have a thick tool bar below image BUT cropping must to a print
size must be quick.
