Hey! I know this was meant for JD, but I couldn't help but answer! I have had the same exact thing happen to me before with my mouse. Usually, there is four things you could do:
#1: Not advised, but you could slam your mouse down onto a hard surface. Don't do it too hard though! This sometimes works. Or maybe give it a good shake!
#2: You most likely need to change the batteries! Most mice glitch and perform poorly when they are low on energy. Try switching the batteries out!
#3: If you really think it is worth the hastle, you can take it to a electronics store such as Best Buy, and try and see if they can fix it.
#4: Buy a new mouse?
