You 99% will not be able to reproduce my problem.
I have project with 2 forms which manipulate another programmes. If i set mainform's FormStyle property to fsSystemStayOnTop all is OK. But if childform's FormStyle property to fsSystemStayOnTop, sometimes this childform disappears.
Generally I need my ChildForm to be on top of Windows Z-Order.

How does Windows detect mainform of multiform application?
Why does fsSystemStayOnTop work only with mainform?
What code is required to make some form (not first appeared) main? Or mayby better how to destroy parental dependences between forms?

What you describe is a bug. Please test with the latest Lazarus Snapshot:
ftp://ftp.freepascal.org/pub/lazarus/snapshots

If it still has the problem, see if it's already reported in the bugtracker.
If not, create a bug report with a compilable project showing the bug.

As I said, it's very difficult to reproduce problem. I deal with over 50 programmes at same time. If there is few programmes, my child form stay on top always.
