Firstly it is not 'drag, drop& move'; it is click, drag& drop! Try
reading the Help a little more closely, you will find that it says:

"The next thing to do is add a voltage-source. While still in Add-mode,
click the 'Source button' (right of the 'Wire button'). Next click and
hold down your left mouse-button somewhere in the picture-box. At the
current mouse-pointer position a new source-object is displayed. Drag
the source-object to the middle of the second wire, just between the two
lower wires-ends of the feedline and release the mouse-button. When
properly positioned a new source is now added."

It does not work as described, when inserting a source on a dipole
wire in the center segment, one of the first things to do in Example1.

Utter Rubbish!!! It works EXACTLY as described!!!

Hold down the left mouse button, drag the source to the segment where
you wish it to be, release the button - exactly as described!!!
