Sorry to keep rambling on about this ... I ammended the script just prior to this thread to demonstrate (to myself anyways) that this problem only applies to moving controls within frames ... and to underline the "neat-ness" (?!) of creating controls as children of the frame ... added (yet) another button to dynamically move the entire frame ... no problem as long as there are no controls underneath the frame. If there are - the same problem still applies (frame refresh).

This script will prove usefull in testing ...
