You both are not understanding. Try to highlight something in a room window or status window. It will not stay highlighted (like it will in the script editor window) so that you can right click to copy it. Once you let go of the left mouse button after highlighting it, it will unhighlight. You have to press ctrl-c to copy it before you left go of the let mouse button.
If you don't understand this, don't try to help with this question. I've explain this THREE times now and other people have agreed that highlighted text doesn't stay highlighted so that you can right-click to copy it.
