Re: GWT 2.4.0 native drag and drop... does it *really* work with IE9?

we found that the drag and drop api is not usable at this point. There
is not a single browser in which this api work as expected. I think
the api is still in development and should not be used at this point,
unless you require part of it to work with specific browser.
