This is a simple thing which works in any fox's editing window, even a modify memo, but not in an editbox: select a piece of text, (optionally press ctrl) and drag the selection elsewhere in the text. You should have the selection moved (or copied) to where you dropped it.

Not so in en editbox. As soon as you click to drag, it unselects.

Is there some simple property which would make this work? Or is there some code to write? I looked at the article at https://hackfox.github.io/section4/s4g356.html, but it's about dragging whole controls and OleDrag, not drag-n-drop editing.
