Is there a way to draw-lock the bow and release with a second click?

Question

Every once in a while, I will notice that I'll draw the bow and it will remain drawn when I release the button. The majority of the time, though, the arrow fires when I release the button. However, I like it when it locks like that because it takes the fatigue out of holding down the button while aiming, especially when it's a dragon fight.

Is this just some beneficial bug or am I inadvertently triggering some in-game feature?

Answer 1

Does it happen more often when you are moving? This thread seems to indicate that this is a bug.
