DO NOT set the dgDragImageIndex to the id of the image. It is an index  
value. Set it to an index.

Again, you should start by checking the id of the image and comparing  
it to the dragImage. Insert this code after you assign the  

put the id of the image "dgDragImage" of me & cr & the dragImage

If the values are the same then the dragImage is being assigned  
properly. Next confirm that the image has the data you expect.

Replace the code that outputs the id of the image with code that  
copies the image data to the clipboard:

set the clipboardData["image"] to the text of image "dgDragImage" of me

Paste the clipboard image somewhere where you can see it. Is it your  
row? If so then the data grid code is doing what it is supposed to.

If both of the above tests pass then you need to track down the image  
in another stack that has the same id as the dgDragImage of your data  
grid. Start searching for an image with the same id in any open  
stacks. Once you find it let us know and we can figure out how the  
engine is searching for the image to use and determine how to fix your
