I think that for a canvas the correct behaviour is contained controls coords relative to the window For ContainerControl should be (and in effect they are) contained controls coords relative to the CC (since it is a window subclass and can live outside a given window) I found in fact that moving or resizing the CC via code resets the coords of contained controls to the correct values so the easy workaround is to put: me.Top = me.Top me.Left = me.Left in every appropriate event like Moved, Resized and Resizing HTH Cool Runnings, Erne. -- / |\ |\ | / |/ | \ | \ |\ | \| \ _______________________________________________ Unsubscribe or switch delivery mode: <http://www.realsoftware.com/support/listmanager/> Search the archives of this list here: <http://support.realsoftware.com/listarchives/lists.html>
