help please. Naga pro middle click is double and triple clicking on links

as the title says. for the past week, week half when i middle click on a link in my web browser to open it in the background. my naga pro will open the link 2 times and sometimes 3 times in the background. ive tried reset the mouse to default, I've tried without synapse installed, as well as with the mouse plugged directly into the pc and the middle click is still double and triple clicking. yes, I've also tried using a different mouse and yes, the middle click worked just fine. even tried with a different browser and still the problem persists. any help or idea would be great and muchly appreciated
