FWIW, I'm still seeing that diagnostic...more below.

I'm still seeing it with wx-3.1, running under 32-bit msw-xp-sp3:
  In file ../src/msw/mdi.cpp at line 1453:
  'SendMessage(WM_MDISETMENU)' failed with error 0x00000008
  (not enough storage is available to process this command.).
so I guess it must be an OS difference.

Not wanting to dismiss it too cavalierly, I tried moving the call to
InitMenuBar() a bit later, to follow this:
but the same message still appears.

I cannot observe any incorrect behavior: the menu seems perfectly correct.
The "not enough storage" message sounds scary, but "task manager" shows
no attempt to grab appreciable RAM, and I have 2 GB free. Should we just
write this off as some goofy msw defect?
