Some, but not all, configuration settings are inherited upon installation of a new version of DMD. Ladder window colors transfer, but Memory View config, ladder 2D/3D, and Start Page config do not, for example.
Is there a way we can export those settings, and/or can you tell us the file location where the settings are recorded so we can back it up, at least for future reinstalls of the same version, hopefully transferable to future versions, and also hopefully XML or some form decipherable by a human, or at least an engineer, so we can migrate manually in bulk.
