  Gamma-ray burst afterglow observations in the Swift era have a perceived lack
of achromatic jet breaks compared to the BeppoSAX era. We present our
multi-wavelength analysis of GRB 060206 as an illustrative example of how
inferences of jet breaks from optical and X-ray data might differ. The results
of temporal and spectral analyses are compared, and attempts are made to fit
the data within the context of the standard blast wave model. We find that
while the break appears more pronounced in the optical and evidence for it from
the X-ray alone is weak, the data are actually consistent with an achromatic
break at about 16 hours. This break and the light curves fit standard blast
wave models, either as a jet break or as an injection break. As the pre-Swift
sample of afterglows are dominated by optical observations, and in the Swift
era most well sampled light curves are in the X-ray, caution is needed when
making a direct comparison between the two samples, and when making definite
statements on the absence of achromatic breaks.
