[texhax] xrightarrow mismatch

The extensible arrow, example below, looks perfect on-screen but prints
with a very slight vertical mismatch between the standard LaTeX rightarrow 
and a
tacked on rule [I am guessing that this is how xrightarrow is defined]

The resolutions are both the same at 300 dpi so where's the glitch please?

\usepackage{amsmath,amssymb}
............................................
\begin{align}
\label{RO2_eqn1}
& \mathrm{RO\dot{O} \xrightarrow[H\dot{O}_2,H_2O_2,CH_3\dot{O}_2]{1.35} 
Products} \\
& \mathrm{RO\dot{O} \xrightarrow[RO\dot{O}]{0.12} 2\:R\dot{O} + O_2 } \\
& \mathrm{RO\dot{O} \xrightarrow[\dot{R}]{0.11} 2\:R\dot{O} }\\
& \mathrm{RO\dot{O} \xrightarrow[RH]{0.083} \dot{R} + RO_2H} \label{RO2_eqn4}
\end{align}
