My mouse which is attached with my GL552 suddenly has auto click on mid-mouse when I scroll it. Unfortunately, it also makes my laptop lag and delay. I don't know why but when I try an old mouse with my lap, it works correctly and I also try to use the attached mouse with another laptop, it also makes that laptop delay and stop. Can you guess me some mouse ? I like the GX860 but I want to find something better and may be cheaper 🙂
