I am using Drag and drop with the "rope" in the image below. The idea is that you grab the rope with the mouse, enabling drag and drop, and can pull the brown sprite down. But occasionally Drag and Drop will break -- it no longer functions and instead, the mouse mouse cursor changes to this:
I have found that this cursor icon also appears in other applications when swapping objects (such as menu items), but I have no idea why it is sometimes triggered in C2, and why it causes D&D to no longer work when it shows up. It usually happens when you get rough with the rope (as in, I was trying to break it to test for bugs), going very fast or having the mouse leave the game window while drag and drop is active.
I'm running in NW.js. Thank you!
