[lmi] wx-2.9.5-rc1 regression

To reproduce:

  File | New | Illustration
  click "Riders" tab

In the "Honeymoon" groupbox, the "Elected" checkbox is enabled,
as it should be. Check it. This should enable the two suboptions
in its groupbox; however, it does not: they remain grayed out.

With "Elected" checked, press "OK", then "Ctrl-E": now the
suboptions are enabled, as they should be. Unchecking "Elected"
should disable them; it does not.

Similarly, on the "Funds" tab, in the groupbox that is also
named "Funds", the "fee" textcontrol should be enabled iff the
radiobox selection is "Override fund", and changing the radiobox
selection should enable or disable the textcontrol immediately;
but it no longer works that way.

These conditional-enablement examples all worked with wx-2.9.3 .
I did not notice whether they worked with earlier wx-2.9.5
snapshots.

We've found a few other examples where conditional enablement fails.
With a particular proprietary product, for instance, the "Elected"
checkbox for "Honeymoon" should be disabled; instead, it is enabled,
but attempting to check it fails (on mouse-down, the checkbox turns
gray; on mouse-release, a checkmark appears for a few milliseconds,
then vanishes, and the checkbox turns white). We wouldn't be able to
release that to our end users.

Conditional enablement seems to work perfectly in many other cases,
such as the rather complicated example of the "Solve" tab.

Whether it works or not in a particular case seems to vary from one
machine to another. For example, on the "Reports" tab, the checkbox
should toggle enablement of all other fields; that works for me,
but not for Kim, although our 'wxWidgets-2.9.5-rc1.tar.bz2' files
have the same md5sum and were built with the same script.

I can't find any similar regression in the "skeleton" trunk:
  http://svn.savannah.nongnu.org/viewvc/skeleton/trunk/?root=lmi
I rebuilt it and ran its unit tests:
  /home/Arktos[0]$cd /lmi/src/skeleton
  /lmi/src/skeleton[0]$make --jobs=6 all install >/lmi/src/log 2>&1
  /lmi/src/skeleton[0]$cd /opt/lmi/skeleton/bin
  /opt/lmi/skeleton/bin[0]$./skeleton.exe --unit_test
  /opt/lmi/skeleton/bin[0]$./skeleton.exe
and everything seemed fine.
