Hang in dialogs (Divinity: Original Sin)

The Enhanced Edition. Version 2.0.119.430. The game periodically does not respond to clicks the mouse on the answer. You can go to the settings, the animation works all sorts of flying leaves, i.e., the game itself is not hanging. If you choose another group member, then the dialog will be removed, and the character who started it, hangs the icon of the dialogue. Anyone had something similar and the bug I found. System requirements the computer fits.
