MouseDown and Scroll bars

I've added a MouseDown event handler to a tree view. So I can display a popup menu when the user does a right click on the Treeview Items.


procedure TfrmTransactions.tvTransMouseDown(Sender: TObject;
  Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
 if Button=mbRight then
  UniPopupMenu1.Popup(X, Y,tvtrans);
By having UniGui 'trap' the MouseDown like this - it's not possible to scroll the items in the TreeView by clicking on the scroll bars. That is clicking on the scroll bar or the up/down arrows of the TreeView has no effect.
Taking out the MouseDown event handler restores normal behavior.
