Are you sure you've got "Use AMS Math" checked, and not "Use AMS Math
automatically"? If the latter is checked, uncheck it and then check the
former, which is disabled if the latter is checked. What's the
difference? The former FORCES \usepackage{amsmath}, whereas the latter
loads it only if you use constructs for which it is needed: and LyX
doesn't know you are doing that in the preamble.
