thanks for responding. The list of dragged drag flavors are not
identical on different OS's/browsers, but the URL type is always
first. On Mac/Safari, the URL type exists as first available drag
flavor, but during the drag you cannot access it. You cannot
access any other drag flavor, either - they all throw this exception.
I'm baffled that a Google search on this exception does not
produce any results. Seems to me that getting the drag contents
while dragging is something you'd regularly do. Especially on OSX...
Thanks,
Florian
