FIXED: Drag and drop behaviour build 42700

Hi,

Dragging and dropping modules from the TDNeuron Toolbar (GitHub - tdneuron/TDNeuron: A deep learning framework for TouchDesigner) does not work for me in version 42700 on Windows 10 whereas it does in 26760.

I don’t know how the drag/drop feature is implemented in this project but thought I would flag it none the less.

Thanks!
Owen

Seems the old way was quirky, in that even if an icon was set to ‘Do not allow Drag’, it would still drag if a parent used legacy callbacks.

This is now re-added to 2020.45470+ for backward compatibility.
Cheers
