On bug 10815 someone posted:

drag from X drop to wine (totalcmd) <---- not working
drag from wine (totalcmd) drop to X <-----not working

The latter case isn't supposed to work because Wine doesn't support that yet
:-).

As for the former case:

trace:xdnd:XDNDDATAOBJECT_QueryGetData (0x68c48c20, 0x32f964={.tymed=0x1,
.dwAspect=1, .cfFormat=15}
trace:xdnd:XDNDDATAOBJECT_QueryGetData application found CF_HDROP
trace:xdnd:XDNDDATAOBJECT_QueryGetData (0x68c48c20, 0x32f964={.tymed=0x1,
.dwAspect=1, .cfFormat=49247}
trace:xdnd:XDNDDATAOBJECT_QueryGetData application didn't find
FileGroupDescriptorW
trace:xdnd:X11DRV_XDND_PositionEvent the application refused the drop

Another mysterious drop refusal. Here totalcmd finds CF_HDROP, but it really
seems to want FileGroupDescriptorW, and since we don't support it, it could be
causing the later failure.

FileGroupDescriptorW is an advanced drag and drop format that allows an
application to read abstract files as data streams. Windows Explorer presents
it to the application on Windows, but it is very difficult to support in Wine
since Linux and MacOS have no similar data format: *nix's X Direct Save and
MacOS's promise data flavors work along similar lines of thought but are
totally incompatible with FileGroupDescriptorW. Wine would have to use a
background thread to pump data behind the scenes or other such.
