I need to be able to drag icons out of a Scrollview as well as drag icons  
into into them, like Edit permits in NS 3.0.  Fortunately, each scrollview  
needs to only accept icons or allow them to be dragged out of the view,  
much like in the Mail.app scrollviews (applications can be dragged out of  
mailboxes, and attachments can only be dragged into new mail). In short,  
my application, needs to both take and give tiff images to the WorkSpace.

Currently, I am modifying ImageText to be able to do this.  I have created  
two documents, one is capable of either receiving an icon while the other  
allows it's icons images to be dragged out.  However, I am not able to  
drag the icon out of my one window.  The icon almost immediatley slides  
back, and the dragFile methods returns with a non-nil value.  If I drag  
the icon fast enough, I can get the image to appear in the other document.   
The documentation leaves me with the impression that I should just be able  
to call dragFile with the icon's pathname, etc. and the rest is "magic".   
Unfortunately, this doesn't seem to be the case.

Has anyone implemented this functionality under NS 2.0?  Any help or  
caveats would be appreciated.

Btw, NS 3.0 is not an option.  In my timeframe, it is vapor.
