Query: Major Flaw That Causes Gaming Errors

After using the explorer 3.0 for over a month I discovered a MAJOR FLAW. If you have a tendency when relocating the mouse on the pad (like when you've gone all the way to one side of the pad but need the pointer to go over even further) if you drop the mouse just a little too harshly, I'm not even talking about hard, it will cause the middle scroll wheel button to activate (it doesn't click but it still activates). This matters if you've reassigned the wheel button to be a certain weapon or some action in a game it will cause the action to happen. I thought I had just abused the mouse so I got new one but it does the same thing. I can not believe nobody else has noticed this issue but I am now sick of this mouse and now need to get something else. I kind of noticed the issue at first but it took me a really long time to realize it wasn't me, it was the mouse causing it every time.
