I am very, very new to Mac having used PCs forever. Have been able to figure out to do many things but have come up with a Stacks problem. I inadvertently, while moving things around in the dock, zapped the downloads, documents and applications stacks which disappeared in artistic puffs of smoke. The information is still available via Finder but I don't know how to restore those folders to their original configuration and place in the dock. The "stacks" pdf says you can create a stack by moving folders to the right hand side of the dock but that doesn't seem to happen. Some of the searching I have done for information mention options to "save as stack" after a right-click but I have no idea how to access this, particularly as I have a new clever mouse which doesn't seem to have a right-click. Any guidance would be very much appreciated. J
