Held object sticks to game window.
When trying to take a screenshot of the previous bug, I found this one.
While holding an object (in this case a character frame from the assign scroll) use (Win+tab) or other shortcut keys that put the game window in the background. When returning to the game, press the left mouse button and the object attaches to the cursor location.
