I provided a patch now. Hope all is ok because this is my first time to work in the community.
Now that I have built a testing-program (depending on built-in MDI methods or using a patched customform.inc) to check all the possibilities i can think of, it shows that inside the main/MDI form there are problems to get the correct zOrder. Therefore the function activeMDIChild does not work correctly. ( In my old Delphi-program i used MDIForm outside the main Form)

That's why I said to Herwig to provide patch. Let we see what it does.
But IMO, win32 need ws implementation, part where mdiarea must be
created and also mdichild handle.
