--- Comment #4 from niermann@physik.tu-berlin.de --- I retested with wine-git version eebf1181f91bbef003dd519f2c2f4ee33f0acc0c (which contains commit f62d8dc58fb3fb5f11a8ab55620ab9b2fbdaf967) and Digital Micrograph (version 2.3.0, 32 bit) behaves like under Windows 7. This bug is now fixed.
For the record, also the test program (comment #2) works now identical under the current wine-git, Window 7 as-well-as Windows 10.
Nikolay, thanks for fixing this.
