Yes, Virginia, there is a Santa Claus. And yes, Virginia, mice do wear out. If you find that you click on things and get anything from erratic to slower to no responses, the issue likely is not your screen and not anything in your programming. Rather, while not dead, the likely problem is your mouse and it is time to send your mouse to a retirement home or assisted living facility. The easiest way to tell is to take one of the mice you have in inventory (and we recommend you always have at least two mice in inventory, preferably three), and install it. If you see that this mouse works perfectly immediately, remove the batteries from your old mouse and dispose of the mouse properly, and put the batteries in your battery inventory drawer.
Note: While it comes in various colors (including black, hot pink, and what they call orange), our Peripherals and Accessories Department (PAD) recommends the 2.4G Ruban mouse. It costs under $9 from Amazon. It only has a sleek design that feels good to the hand, it also has an on/off switch that extends the battery life.
