Why it is impossible to drag an image into UV/Image Editor and Node Editor? A strange thing happened.
On my best computer (Windows 8.1, CPU i7 with 32 GB RAM and 3 GTX770 onboard) it is impossible to drag an image into UV/Image Editor and Node Editor. The mouse pointer is a denied symbol...
On my iMac this works.
I tried to reinstall and set as Default Settings but nothing...
Can you help me?
Thank you.

I do not believe it is. You will need to add an "image texture" node, then select "open image". From there, locate your image. If it is a video, add a "movie clip" node and do the same. Hope this helps!
