Well, there isn't anything wrong with it such that I've noticed in any other games - but ah well. ^_^; It seemed to just happen sometimes, somewhat at random. Who knows, maybe I held down the mouse button for longer on some clicks and it thought I meant to keep shooting? (Not sure if it works that way.) If I get time in a bit I'll try again and see if that was it (i.e. if I can replicate it intentionally)
