Button 4 & 5 - Click and Drag too sensitive [enhancement]

[mktoaster]

Description

For side buttons 4 and 5, I would love to see the Click and Drag feature less sensitive, so it performs the Click action and not the Click and Drag action from the small natural movement that comes from clicking the button

Rationale

When pressing the side buttons 4 & 5, there is a natural motion from the button press. That motion is picked up as a Click and Drag function. So instead of pressing Button 4 to go Back, it will instead switch spaces.
Modifying the tolerance would be helpful.
