Bug ID: 58518
           Summary: Drag'n'drop from/to Linux file manager not working -
                    Olympus Master 2: fixme:imagelist:ImageList_DragLeave
                    DragLeave hWnd != DragEnter hWnd
           Product: Wine
           Version: 10.12
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

Note:
1. Olympus Master 2 is not officially available anymore but I can provide a
copy of the program folder if required.
2. Similar issues appeared with another Windows software, so the issue is
probably more general.

a. When I drag file(s) from Nemo to Olympus Master 2 or the other way round, I
receive on the commandline:
0024:fixme:imagelist:ImageList_DragLeave DragLeave hWnd != DragEnter hWnd

b. While dragging from Olympus Master 2 to Nemo is impossible (hand cursor with
a stop symbol), the dragging from Nemo is in principle possible (hand cursor
with green +). Olympus Master 2 opens a window to "register" the file(s), i.e.
asking to choose an album. However, it hangs without further messages on the
commandline. I can only stop with Ctrl + C. Same message on the commandline.

c. It works in both directions when using Olympus Master with the Windows file
manager Explorer++ from https://explorerplusplus.com/.

d. Similar issues appear when using Explorer++ with Nemo. Dragging from Nemo to
Explorer++ works as expected as long as the file does not exist in the target
folder, i.e. the file is copied. If the file exists, an empty window is opened
(to confirm the overwriting) and Explorer++ hangs. Dragging from Explorer++ to
Nemo is again impossible (hand cursor with a stop sign). These messages appear
in all cases:
