<p>Hi Bob,<br>
</p>
<p><br>
</p>
<p>I think I see now what I missed out in my explanation. Ordinary morph drag and drop should not be affected by my change at all. <br>
</p>
<p>Actually you can still drag and drop morphs like before (even openInHand and dropping it afterwards). </p>
<p><br>
</p>
<p>What I intented to change was the drop behavior for the mechanism for opening a morph for an object dropped in the world (basically PasteUpMorph>>transferMorphConverter:).
<br>
</p>
<p><span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px; background-color: rgb(255, 255, 255);">For example, </span>my method checks whether the dropped object is a Model and if so tries to open it with ToolBuilder.<br>
</p>
<p><br>
</p>
<p>The drag starts in PluggableTreeMorph>>#startDrag: to answer your initial question.<br>
</p>
<p><br>
</p>
<p>Bests<br>

<p>Well before the change, the morph would have opened anywhere in the world. Most of the time that was not close to the hand.<br>
</p>
<p><br>
</p>
<p>You are right though, that the new behavior look weird too... Maybe this is because it looks good for dragging menu items?<br>

<pre>This allows for more "intuitive" drag and drop behavior. When I drop something into the world and a morph is opened for it than the morph is displayed at the position where the element was dropped. For a simple example so the gif attached.
