Bug is related to winamp, a windows music player (www.winamp.com). Other
applications may be affected by this bug.

Problem:
Every File drag and dropped to the playlist-window of winamp will duplicated.
It generates double entries for every file dropped to the playlist-window.

Version of wine:
This bug has been introduced since version 1.3x. In wine 1.2 everything is
fine.

Details:
If you drag drop a file to the main window of winamp, no duplicate entries will
be generated. But if you drop a file to the playlist-window (a window within
the winamp application), you will get two entries (duplicated). So it seems to
me that the bug is connected to how the drag drop code specifies the target
window.

It seems that with wine 1.3 new code for a better drag and drop functionality
has been introduced. But also leading to a bug with duplicate entries.

Maybe someone can fix this? Would be nice :-)
