B4J Question Help minimizing an undecorated form (tried setIconified)

Hello.
My app has a main window which shows all the options and submenus and covers most of the screen. It is "undecorated". The problem is, when I open other forms from that main form, they don't show as separate "tabs" in Windows, so as soon as I click on another part of the screen, the smaller forms disappear behind the my app's main window. So the only way to see them is to minimize the main window and get it out of the way. But I haven't been able to do that. I HAVE tried setting SetIconified to true, as the forum suggests, but that doesn't exactly minimize the window; it makes it totally disappear! or turns it into a rather empty bar in Windows Taskbar and I can't bring it back up.
Please tell me what I can do to minimize the main window or at least make sure it stays "behind" all other forms opened in my app.
Thank you so much.
