Worked fine last time we turned it on.

It's back in the closet for the time being; was not planning to fire it up again. Jason has dibs on this thing if he can get back to me within a reasonable time. Come back, Jason? Otherwise I'll update you all on status of availability. TY all for the interest. Liz J
