So according to Jon here:
It's actually a bug. So it should be fixed in the next update. So martyprod, it's better to wait till the new version of DOpus comes out and use the script again. The workaround I had earlier worked only if you manually got to a tab and then paste a copied/move file/folder into it. So it's definitely not idea. Once the fix for DOpus is out, my initial version of the script should work perfectly.
Thanks Jon!
