It seems that RealChildWindowFromPoint doesn't recurse into deeper 
windows, except for HTTRANSPARENT windows, where it recurses deeper than 
ChildWindowFromPoint to find a window that doesn't return this hit-test 
(except if it is a static control). What a mess for developers...

Two comments on the patch:
1. Please send patches as text attachments. Usually, renaming to .diff 
or .txt before attaching is enough to make this happen.
2. "+    FIXME("partial stub. HWND: 0x%lx\n", (DWORD) hwndParent);" -> 
don't cast hwndParent to DWORD, just change the format to %p.

Thanks for the patch,
