Apple concurs:
http://developer.apple.com/technotes/tn2007/tn2196.html#APPLE_AWT_DRAGGABLEWINDOWBACKGROUND
I'll add a note to that effect in the javadoc.

Hi Timothy,
We found it. The problem was that we were calling setTransparent after the window is set to visible. The transparency was working just fine this way, but apparently the "apple.awt.draggableWindowBackground" should be set before the heavyweight peer for the Window is created, otherwise it does not take effect. It works great now!
Cheers, Yana

Oups, sorry Timothy. Actually it seams that even with just calling setWindowTransparent we get the same behavior. We'll make some more tests and see why this fix does not work in our case.
Thanks again! Yana

Thanks for your reply, Timothy!
Yes, we're using OSX. We've just tried with the new version of WindowUtils and here's what happens: Only calling WindowUtils.setWindowTransparent(mainFrame, true) fixes the drag and drop problem but we get a 100% transparent window. This is not quite what we need though so we're setting a semi transparent content pane to our window, which reverts to the old drag behaviour. Is there a way to have the semi-transparency and not have the window draggable? Are we missing something?

In our application we're using WindowUtils and AlphaMaskDemo as a base
BTW, there's nothing in AlphaMaskDemo that's necessary for transparency. Once you call WindowUtils.setWindowTransparent(w, true), individual pixel transparency will be preserved.
Originally AlphaMaskDemo had all the grimy details of per-platform transparency implementations, but all of that is now encapsulated (and cleaned up) in WindowUtils.
