Screenshot: Add/Remove Programs missing from Task Manager

If Wine File Manager is used to open Add/Remove Programs, then there is:

* a window for Add/Remove Programs

– but no separate listing for the window in (for example) 
  Task Manager of KDE Plasma.

After Wine File Manager closes:

* there remains a window that's not in Task Manager

– screenshot attached.
