Not the only weird behavior from a Sigmamicro controller. Some Sigmamicro keyboard-touchpad combos found in laptop/convertibles expose the touchpad as a mouse and then report some touchpad gestures as if they were keyboard actions, with hardwired key combinations corresponding to keyboard shortcuts specific of Windows. Evsieve (https://github.com/KarsMulder/evsieve) can be your friend in working around the issues that come out of that.
