I really appreciate your help, but the Alt/Opt key and clicking on the mouse is not causing crosshairs to appear on my second image. There must be a setting that is wrong or something wrong in the menu.
Thank you.
As far as i know, photoshop cs3 was the last version to have that feature without having to change any settings.
In photoshop cs4 and newer, one needs to disable Use Open GL Drawing or Use Graphics Processor in order to see the source Crosshair in the clone source document when cloning from one document to another.
So, first turn off Use Graphics Processor in Edit>Preferences>Performance, restart photoshop, then open your two documents
and you should now be able to see the trailing Crosshair in your source document.
