(OP)
I want to display one instance of any of several child forms and switch between them.

snippet from main form (frmTest fsMDIForm, frmPage1 fsMIDChild) ...

void __fastcall TfrmTest::Page11Click(TObject *Sender)
{
    if (!Page1)
    {
      TfrmPage1 *frmPage1 = /bnew/b TfrmPage1(/bthis/b);
      Page1 = /btrue/b;
      frmPage1->Show();
    }
    else
      frmPage1->BringToFront();
}

where /bbool/b Page1 is initially /bfalse/b, and Page1 is doing nothing.

Instance is created OK, but when the menu item is clicked a second time ERROR!

Access violation at address 41303AE6 in module 'VCL35.BPL'. Read of address FFFFFFFF.

Am I doing something stupid?

Any suggestions would be welcomed.

Roy Thomas.
