I have been encountering a problem with my bow. I have been having this problem for a while now, on more than one character.
Sometimes, when I draw back the bow, the arrow will be released early (almost like I only click LMB, rather than holding it down). Often when this happens it will go on for a handful of shots. A new thing I noticed recently is if I try and persevere, the arrow sometimes becomes 'stuck' in the drawn phase, so I am moving about with the bow full drawn, without holding down LMB. These problems weren't really an issue at first, but now I have an enchanted bow, it's costing me charges each time it messes up. It's also very annoying to get into the perfect position for a sneak shot, only to have the bow fire a few feet in front of me, and alert my target.
I have never seen this problem in any other attack (sword or spells for instance). I also spend a little time on my desktop drawing out selection boxes and holding them there, to see if it was my mouse at fault, but it doesn't seem to be.
Has anyone else seen this problem, and is there a fix for it?
