Ctreectrl under Win7/Vista

Under Windows XP, when you drag and drop an Ctreectrl item, it will create a ghost image of
the item icon and text. But, I ran the same program under Windows 7/Vista, and the item text
is missing for drag and drop. Just the icon is dragged.

The drag image is created using CreateDragImage().

Sample program can be downloaded here:

Just wondering if anybody has experienced this problem before.

Edit:
Ah, nevermind.

Is it 64 or 32bit OS?
