im working on my menu builder and ive stumbled across a problem, everything was working well until i tryed to add a combo box

this is the code to add some controls

Code:
              Control := CDXUTStatic.Create(Dialog);
              (Control as CDXUTStatic).SetLocation(SpinEdit1.Value, SpinEdit2.Value);
              (Control as CDXUTStatic).SetSize(SpinEdit3.Value, SpinEdit4.Value);
              (Control as CDXUTStatic).Text := StrToPWideChar(Edit1.Text);
              (Control as CDXUTStatic).Default := CheckBox1.Checked;

              Dialog.AddControl(Control as CDXUTStatic);
              strType := 'Label';
              Result := True;
Code:
              Control := CDXUTButton.Create(Dialog);
              (Control as CDXUTButton).SetLocation(SpinEdit1.Value, SpinEdit2.Value);
              (Control as CDXUTButton).SetSize(SpinEdit3.Value, SpinEdit4.Value);
              (Control as CDXUTButton).Text := StrToPWideChar(Edit1.Text);
              (Control as CDXUTButton).Default := CheckBox1.Checked;

              Dialog.AddControl(Control as CDXUTButton); 
              strType := 'Button';  
              Result := True;

(just to give you an example), that code works fine and the control (CDXUTControl) is added to the dialog fine.


however the following code doesnt work

Code:
              Control := CDXUTComboBox.Create(Dialog);
              (Control as CDXUTComboBox).SetLocation(SpinEdit1.Value, SpinEdit2.Value);
              (Control as CDXUTComboBox).SetSize(SpinEdit3.Value, SpinEdit4.Value);
              (Control as CDXUTComboBox).Default := CheckBox1.Checked;

              for iLoop:=0 to Memo1.Lines.Count -1 do
                (Control as CDXUTComboBox).AddItem(StrToPWideChar(Memo1.Lines[iLoop]), nil);

              Dialog.AddControl(Control as CDXUTComboBox);
              strType := 'Combo Box';
              Result := True;
the access violation is in UpdateRects on line pFontNode := DXUTGetGlobalDialogResourceManager.GetFontNode(m_E lements[2].iFont); (in the setlocation)


ive got, labels, buttons, check boxes, radio buttons working fine so far, this is the first one to crash.

any ideas?
