What do you mean "When I click my mouse a lot?" What are you clicking on?

In a game. Not like clicking a lot in a short amount of time. But when i click alto in long period of time in a game.

Maybe this is a problem with rotating the mouse wheel while you hold down the Shift key.

There are various mousewheel.with_*.action prefs that control the action of the mouse wheel

• action: 0=lines, 1=pages, 2=history , 3=text size

You can consider to set these prefs to 1 to make them act as the default action.

• mousewheel.with_shift.action
• mousewheel.with_control.action

I'm just clicking. I'm not using shift nor the mouse wheel.
