Hi. Has anyone had a problem where the tablet causes the mouse to go crazy, begin clicking everywhere and act weird? I'm convinced it's the tablet as I've tried multiple mouses, changed USB ports, and the tablet has been the constant issue. It works just fine but every now and then causes the mouse to click and move abnormally even if I'm not touching any of it.

I've looked up info but most results showed other brands, I already tried re-installing the driver and nothing has changed. Does anyone know what the issue could be? I have a Star G640 (photo attached) that's only a year old. I would appreciate some help. Thanks in advance.
