  Triple differential dijet cross sections in e^\pm p interactions are
presented in the region of photon virtualities 2<Q^2<80GeV^2, inelasticities
0.1<y<0.85, jet transverse energies E_T1>7GeV, E_T2>5GeV, and pseudorapidities
-2.5 < eta_1^*, eta_2^* <0. The measurements are made in the gamma^* p
centre-of-mass frame, using an integrated luminosity of 57pb^-1. The data are
compared with NLO QCD calculations and LO Monte Carlo programs with and without
a resolved virtual photon contribution. NLO QCD calculations fail to describe
the region of low Q^2 and low jet transverse energies, in contrast to a LO
Monte Carlo generator which includes direct and resolved photon interactions
with both transversely and longitudinally polarised photons. Initial and final
state parton showers are tested as a mechanism for including higher order QCD
effects in low E_T jet production.
