Right - On Drag Over If On Drag Over returns -1 The cursor is set to a disallowed cursor (Circle with diagonal line), and the drop action is NOT allowed. If On Drag Over returns 0 THe cursor is/becomes an allowed (copy/drag-n-drop cursor), and the drop action is allowed.
What I am seeing, and traced (BTW - Tracing ON Drag Over is risky as it can quickly stack up calls and crash 4D) is that the On Drag Over event is firing, and my code returns 0 (everything is OK), the cursor stays (becomes) the 'allowed' (copy/drag-n-drop) cursor. BUT the action of releasing the mouse button (dropping) does NOT trigger the On Drop Event. I have tried reversing the order of the conditional tests i.e. Cose of :(On Drop) :(On Drag Over) vs case of :(On Drag Over) :(On Drop) still with no effect.....
