SUMMARY When the user is trying to drag n' drop an analog clock from widgets explorer onto panel that contains fill applets it creates a flickering when the mouse is above a fill applet
using LayoutManager javascript for this is totally non sense... reparenting all the time with no real reason in order to move an applet at correct position while using c++ for this is totally achievable... probably solution is to create a c++ LayoutManager singleton library which is going to be used from all containtments.
this is fixed from all new c++ FastLayoutManager
