May be it is some bug in my MS Window XP instalation that it receive WM_NOTIFY from both window correctly.
I'm not sure I understand you here. What do you mean by 'both windows'?
I mean both windows from example program.
Ok. You will see after your test. I hope that my example code will be helpful for you.
