Somehow the child windows are no visible.
How do i know that?
I created a simple Form + Button project with lcl-fpgui.
Examined the created application with WinInspector www.*windows*-*spy*.com/
The WS_VISIBLE flag is not set in styles property
Set WS_VISIBLE flag using "Edit Windows Styles" -> the child window
appears and works as expected.
