If you still have some problems with the built-in protection system, then you should install the plugin ECC+.
Thanks a lot for your wonderful review, we are glad that our module helped you.
Regarding the flickering, it seems it is a browser issue (not coding issue), since we tested it in Chrome (which is very light browser), and it moved smoothly, but Firefox, it flickered when moving.. it is rendering issues with the browser itself..
But as you said, who wants to resize a window anyway :)
