We study the triangle Wilson loop in 2+e dimensions to order g² in the lightcone gauge with Mandelstam-Leibbrandt prescription. The complete result agrees with the calculation performed in the Feynman gauge. However, at intermediate stages the new 'ambiguous' terms of the form w^{[(e)/ 2]-1}e^-1 appear which are not controlled by any sort of Ward identity.
