Mouse Map not working

MBUTTON is set to broadcast 1.

1 is on the whitelist, and gets broadcast when I press it manually.

When I press MBUTTON (mousewheel click) nothing is sent to the windows.

MX1000, SetPoint 4.60.122 on Vista x64. Mouse wheel click is set to "Middle Button" in setpoint. I've tried changing it to something else and changing it back to Middle Button (as suggested in another thread) with no result.

Ideas?

Meh, AHK remapping works fine, simple workaround.

Code:

---

XButton2::-
MButton::=
