Is there any way to use the mouse buttons in this game? I have a Logitech Mx518

BUMP

It's pretty simple really, but I admit I ran into the same problem

Settings > Controls > Action Mapping > then click on "Device" in the bottom right corner of the screen. Should switch to "Mouse" instead of "Keyboard" and you're all set to map your mouse buttons.

Shrug, I use logitech setpoint to remap the buttons on my mouse.

Setpoint 4.80 works fine here but my mouse is the Logitech G5 gaming mouse with 7 programmable buttons on it in addition
to the standard left/right click buttons.

Maybe the one you have can use setpoint too to program its buttons as you see fit.

As for in game I see no way to do that, one has to use third party software. Not a problem for setpoint users , shouln't be anyway. I use it for
customizing my mouse layout for all my games.

good luck.
