I'm dragging graphic parts onto a diagram. I use drag clones. When I click on one of these graphics, the code positions the drag clone over that graphic and then makes the drag clone visible.
El problema era que el solo la primera vez I try to drag cada drag clone, and if I mousedown and drag quickly, the screen would produce a circle-slash symbol at the same time the drag close appears. The drag clone would then misbehave somewhat.
It took me a while to figure out, but watching closely I saw that the circle-slash appeared before the drag clone. And then, the two comments below explain how I solved it.

I figured out that the circle-slash is caused because the system is telling me I can't drag the static "diagram part" graphic, the one that the drag clone replicates.
And the solution to the problem of the static graphic starting to drag and generating the circle-slash was to make it an ImageButton with an OnClientClick attribute to stop the postback, like below. These inputs are then not draggable like an by itself would be.
