thanks - that did the trick!

Not really. For any class you want on LyX's list, you need a layout
file (so LyX knows how to render things on screen). LyX automatically
installs layouts for a lot of "common" classes ("common" being defined
by the developers, I guess). For any other class you add, you need to
manually add a layout file. In most cases you're stuck creating the
layout file yourself (unless some other kind soul has posted one).
Beamer is somewhat unique in that the package developer supplies a
layout file, but otherwise this is business as usual.
