Possible Bug in Amaya 9.52: MathML saving and re-rendering

Hello,

I am running Amaya 9.52 under Win XP for keyboard entering of maths expressions via Amaya GUI and saving them in xhtml (containing MathML) format.
Expressions look fine when entered however if the resulting html file is saved, closed and reopened, it is not rendered properly and the string 



xmlns="http://www.w3.org/1998/Math/MathML"



is rendered together (in the middle of, on top of, etc.) with the maths formulae.

A look into the source shows the above string appearing between math expressions, within <mo> tags, etc. (an example file is attached).
So far, I have been cleaning up all my saved files and then they are OK - render beautifully in Amaya or anywhere else.
Please let me know if there is a fix for the above problem.

Regards,
-Jeliazko Polihronov
