Magic Mouse Sensitivity

I have a magic mouse that is way too sensitive to the touch. I have tried every suggestion here and at other sites, with no success. I took it to an apple dealer and he did a great job of trying to figure it out with no success. This is frustrating and I really think Apple needs to redesign this and make it better. I use Filemaker 19 most of the time and when trying to work on a layout or anything. When selecting the field in layout or browse the whole layout jitters up and down and over. Please help! This is driving me crazy.
