I notice that many times after I load a save, the mouse is just... broken. Not functioning like it should.

Like for example when I use the mouse to move, the cursor just gets stuck in arrow mode and moves my character around. Clicking on examinable objects or the character to open inventory does nothing, although the I button still work even though I cannot choose and use the item. I can't seem to find a fix other than reloading and hoping for the best.

Anyone ever experience this? Any idea what might be the issue or how to fix?
