Treeview Regression

[Drew "DanteAliegri" Ogle]

There has been a treeview regression, since at least 20030115,
I assumed someone would take it up, but noone has.
I will try to fix it, but a rather simple testcase ( ~200 lines of C )
is at http://open-socket.dyndns.org/~dante/treeview-testcase.tar.bz2

What appears to be happening, is when the dialog recieves a message
that is WM_NOTIFY , it excpets the lparam to 1) be
LPNMHDR, and lparam->code to be TVN_SELCHANGED.
the lparam->code that wine appears to be returning is 0.
