I have fixed my problem on Win98.  I am writing a Unicode application
using Unicows for Win98 compatibility.  My problem was caused by the
fact that the UNICODE version of the Win98 native tree control returns
different messages than the non-UNICODE version.  I added handling for
both messages and my problem was solved.

I will be submitting the patch to wxWindows, but if you'd like to make
the change yourself:

In File: "wxWindows\src\msw\treectrl.cpp"

In Function: bool wxTreeCtrl::MSWOnNotify(int idCtrl, WXLPARAM lParam,
WXLPARAM *result)

Replace:
 case TVN_SELCHANGED:
with:
 case TVN_SELCHANGEDW:
 case TVN_SELCHANGEDA:

AND

Replace:
 case TVN_SELCHANGING:
with:
 case TVN_SELCHANGINGW:
 case TVN_SELCHANGINGA:


Recompile wxWindows and it should work.

Regards.
