Bug ID: 47717
           Summary: Main window and side windows do not work properly
           Product: Wine
           Version: 4.12.1
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

      Distribution: ---

To the left and right of the main XMPlay window are sub windows that allow for
configuration of the equalizer (Left sub-window) and playlist (Right
sub-window), along with other various options per sub-window, when the tabs are
double-clicked. When the tabs are double-clicked again to collapse, the
sub-windows collapse, but on TOP of the main window, instead of underneath,
which then make the product unusable... until the sub-windows are reopened and
access to the main window is regained.

Expected function: for the sub-windows to move back under the main window when
collapsing.
