This works. But in my top-level form i've got a button "open antother session" which does DO FORM Topform. So antoher session of my application is started.
Now when i click the "Change Topform Caption" - button the caption of the topform of the last started session is modified instead of the currently active session.
All my topforms have the same name: " Topform" because it is the same form.
So as long as we are talking SDI it works, as soon as we go MDI we get problems.
