If you want to post those 2 expressions, I'll see if I can spot something.

don,
system flags ->2 and ->3 are set to symbolic.
to simplify the problem my calc. does not simply the example that i referred to in users' guide.  but it asks to switch to approximate mode.  when i said no, i get he error
> message "EVAL Error: Mode switch cancelled"
pretty weird huh!!!
