Unbind native mouse button 4 and 5

[nyahs]

Hi,

I'm using mouse button 4 and 5 for resting one turn and auto-explore.
I'm having some issues when my mouse cursor is on the left or right chat window. The text scrolls up or down and it's very annoying.

I don't know how can I stop this behavior. I've looked in the key bindings setting but didn't find anything.

Thanks !
