Memory Question

A reader writes about using the Duplicate command on a large image, and having his Windows computer abruptly crash.

The key to unravelling this mystery is in how the Duplicate command works. Image>Duplicate loads a copy of the image, layers and all, into memory. It doesn't spit it out on to your disk, as such, until you save the copy.

So, if you are working on a large layered file, you'll need check to make sure that you have enough memory, an external speedy scratch disk, or other such aid to assist you in duplicating an image.
