AMS 2000 Classification

[Sandor Szabo]

Hello,

I use LyX 1.4.3-5 in XP. I use article(ams) document class.
In the scroll-down menu there is a 'subjectclass', which
produces the '1991 MSC' instead of 'MSC2000'.
What could I do if I do not want to type by hand the MSC2000?

Thanks,
           Sandor
