I am trying to drag and drop images in a panel. The panel accepts the image fine but when the mouse is released the image moves off screen and the panel resizes. I have tried manual and automatic drag-mode in the TImage properties and also false and true in the TPanels autosize property. I cannot get the drag and drop operation to behave in a sensible way. I also experimented with a formulae to calculate the position of the mouse down coordinate and the mouse up coordinate to specify a location for the image but it behaved erratically. Can anyone tell me if this is the right track or am I missing something?
