Query: First Measurement of $\Gamma(D*+)$   We present the first measurement of the D*+ width using 9/fb of e+e- data
collected near the Upsilon(4S) resonance by the CLEO II.V detector. Our method
uses advanced tracking techniques and a reconstruction method that takes
advantage of the small vertical size of the CESR beam spot to measure the
energy release distribution from the D*+ -> D0 pi+ decay. We find the D*+ width
equals 96+/-4(Statistical)+/-22(Systematic) keV. We also measure the energy
release in the decay and compute m(D*+)-m(D0) =
145.412+/-0.002(Statistical)+/-0.012(Systematic) MeV/c**2.
