Hi there. I just bought a macbook and i have only ever used windows. I have a few quick questions: Does finder ever close? The little dot under the icon is always 'on', and i don't see an option to close it. When you drag something (like a stack) from the dock to the desktop, why does it disappear? Is it just removing the shortcut? Last but not least.. is there a way to continue downloads when the computer goes to sleep? Thank you so much. This group seems very knowledgeable!
