 Yes. There is a minor detail: with "Windows Version" set to XP I do see at
least the effective date control itself, and not just its label, while with
"Windows Version" set to "10", I only see the label. I think I do have an
explanation for this, however: wxWidgets assumes that Windows >= Vista (and
I confirmed that the date picker control is still shown for "Windows
Version" set to "2003", but disappears when it's set to "Vista" or later)
supports DTM_GETIDEALSIZE message which allows the date picker to tell us
how big it wants to be. Wine doesn't support this message, however,
independently of the version, and this explains why the control is
invisible: it simply has 0 size. I've created a ticket for this in Wine
bugzilla: https://bugs.winehq.org/show_bug.cgi?id=44680 and, as mentioned
there, it would be possible to work around this in wxMSW itself, but I
don't know if it's worth it, especially as you can only use "XP" as version
anyhow for different reasons.

 I still don't have any explanation for why don't I see any other controls,
even with "XP" version, nor why is nothing purple for me with "10". I could
try debugging the former and probably will end up doing it just because
this is so mysterious, even if it's not particularly important as I never
test lmi in Wine anyhow (I do it on either a physical machine with MSVC or
in a VM with MinGW). Arguably, the first thing I should do is to try
building lmi using the official makefiles under Linux, which is something I
had never done yet...


GC> Are you running wine in a chroot?

 In a Buster chroot on a more or less standard (there is some extra stuff
needed to make all the hardware on this notebook to work, but it really
shouldn't be relevant here) Debian Stretch system.
