I hope you are more awake now ... please could I have more information.
I've recently fixed several bugs in DnD and was hoping I had it working 
pretty much fully as documented at last (I guess that may not be the same 
thing as working exactly like MacOS-X ... but I hope it is).  However, until 
now the mouse offset argument when starting a DnD session has been ignored 
completely, and as there is no experience using it, I'm not sure I've got it 
right ... but that's one possible place to look for changes in behavior.

Anyway ... If you could give me exact descriptions of where this appears 
wrong (and ideally the CVS version and the point in the GWorkspace/GNUMail 
source code that the DnD is initiated) I can make more of an attempt at 
understanding iwhat the issue might be.

I've looked at GWorkspace and dragging icons on the shelf.
The DnD here appears to be initiated in [FSNIcon(DraggingSource) 
startExternalDragOnEvent:] and this code appears to say that the bottom left 
corner of the image should be positioned at the current mouse location.  
Looking at it on my system, the visible icon image actually appears a few 
pixels above and to the right of the the mouse pointer ... if the image has 
a transparent border it could explain that small offset, if not ... I guess 
there is a bug there.  Is that the problem you are referring to?
