I let my son use my old Extreme 3D, because it was doing the same thing.
It sounds like either a design flaw, or something inheirent in one of the components.
That might be worth writing to Logitech about. It shouldn't matter how old the stick is. A company needs to know about a recurrent problem so they can fix it. It's a Quality Control issue, no doubt.
You never know... You could get a replacement part out of them, if you worded the letter right.
