Hi Michael,

thank you very much for your help. I'll add a version check in the next NE release.

if (moi.majorVersionNumber<4) {
	this._touchpad_callback = this.bindFunction(this.touchHandler, this);
	canvas.addEventListener("touchstart", this._touchpad_callback, true);
	canvas.addEventListener("touchmove", this._touchpad_callback, true);
	canvas.addEventListener("touchend", this._touchpad_callback, true);
	canvas.addEventListener("touchcancel", this._touchpad_callback, true);
}
