I am hopeful that as a complete Newbie I might be allowed a certain quota
of dumb questions before getting flamed, in the thought that I will get up
to speed quickly.  I read the questions and answers in this list and try to
figure out what is going on.   So....the question raised by "Odd Problem"
prompts a question:  I am in the process of getting my first test bed set
up (for an 18F452) and need to order a 10 Mhz crystal.  They seem to come
in two flavors:  serial, and 20pF.   My understanding is that the 20pF is
the preferred one.  If that is true, is it still necessary to use the two
caps to ground from the leads???
