           Summary: shell32:progman_dde - test_parser() sometimes gets
                    DMLERR_NOTPROCESSED in Wine
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2

shell32:progman_dde - test_parser() sometimes gets DMLERR_NOTPROCESSED in Wine:

progman_dde.c:274: Test failed: expected DMLERR_NO_ERROR, got 16393
progman_dde.c:275: Test failed: directory should not exist

See https://test.winehq.org/data/patterns.html#shell32:progman_dde

Where 16393 == DMLERR_NOTPROCESSED

The first known instance happened on 2023-03-02: this did not happen in the
previous 6 months. Since then there has been a bit over 1 instance per week so
it seems likely this is caused by a commit in late February:
