Game Input MultipleXer

In my blackops config i've got my forward mouse button for tactical nades:
<button id="l2">
<device type="mouse" id="0" name=""/>
<event type="button" id="BUTTON_X2"/>
</button>
But whenever I press it in sixemu, It lowers the DPI on my mouse. This behavior is corrected when I run output-GUI.(but then i cant move) Does this happen to anyone else? :S
(Windows, usb)

What's the mouse?

Did you configure something in the Logitech setpoint software?

Please copy-paste your config file within a Code tag.

Actually, I just turned off Logitech setpoint and it appears to have been resolved... Weird considering that I didn't set anything to sixemu.exe haha:).

This could be good for FAQ under button glitches*
