I have Windows 10 Pro 64bit and a Windows 7 Pro 64bit computers with TMG 9.05 gold edition loaded on both. The Windows 7 unit will allow me to drag and drop exhibits from file explorer but the windows 10 unit will not. Is there a parameter I am missing? My older Windows 8.1 Pro unit had the same problem. I use all external exhibits. I use two monitors most of the time on both units.
