Issue with the Naga Trinity scroll wheel

I've been experiencing a very annoying issue with the scroll wheel, where when I press it in order to scroll on a web page - it sort of "turns itself off and on", meaning the scrolling can stop all of a sudden without me stopping pressing the scroll wheel. An even more annoying bit is that sometimes, when I close a web browser's tab by pressing the scroll wheel while hovering over a tab - the mouse presses twice (or more), and it closes multiple tabs. What could be the issue? I've searched this issue and people suggested blowing air in between the scroll wheel air gaps, but that didn't resolve it. Thanks in advance.
