Hi Alexander,
In the process of debugging I also determined that Windows doesn't seem to send this message to parent at all (tested on win98-Qemu, winXP SP2-Qemu and winXP SP1 normal installation). So I'm deleting this second call altogether and a conformance test for this situation will be included in the next patch.
Under some circumstances, it must - see bug 9233 (and my patch at url below) http://www.winehq.org/pipermail/wine-patches/2007-August/042660.html http://www.winehq.org/pipermail/wine-cvs/2007-August/035236.html
I debugged this through to the point where the parent was definitely retrieving the information (I watched spy logs of the application in question) and I believe reversing this patch will break radmin again... It's a free download, can you please test you havent regressed that application with the patch
