How to disable/remap mouse scrollwheel?

[th0masp]

Hi,

I'm looking for a way to disable or remap the mouse scrollwheel, ideally application dependant but if it can be made to stop working entirely I won't complain.

I actually have normally no mouse connected but some actions of my Wacom Intuos tablet annoyingly get interpreted as scrollwheel actions in certain applications, hence the desire.

• Google fu leads me to variations of this tip: https://superuser.com/questions/431805/mac-os-x-lion-possible-to-disable-scroll-wheel - but I don't have an option to disable scrolling entirely in Preferences/Universal Access (even if I connect a mouse temporarily in the hope that it unlocks settings)

• As far as I can see there's nothing in the Wacom tablet driver options to alter the behaviour

• The applications in question do not have the option to disable the scroll wheel

• Better Touch Tool does not recognize the mouse wheel at all, just the buttons

• KeyRemap4Macbook confuses me, not sure if it can be made to achieve this?

Any way to get this solved?


Edit: to clarify - Wacom pen input (pen down/up) gets interpreted as mouse wheel input, it's not related at all to the various buttons and the wheel on the tablet itself.

I've played with KeyRemap4Macbook a little more - I can see in the event viewer that a Pen down event sometimes - but not always - triggers scrolling which is causing my issues.

Then tried to insert this -

<autogen>__KeyToKey__ KeyCode::VK_MOUSEKEY_SCROLL_LEFT, KeyCode::VK_MOUSEKEY_BUTTON_MIDDLE</autogen>
<autogen>__KeyToKey__ KeyCode::VK_MOUSEKEY_SCROLL_RIGHT, KeyCode::VK_MOUSEKEY_BUTTON_MIDDLE</autogen>​

into the configuration file and activating it through the interface to replace the mapping for mousewheel events up/down with a single middle button click but it does not have an effect (also tried with mousewheel left/right and replacing it with a regular keystroke).
Anybody know what the issue might be?
