Hi Hadley and Paul,

thank you a lot for the suggestions...

However, i had also emailed Greg Snow  (author of my.symbols() function)
personally... and Greg has emailed me back with a fixed version of the
my.symbols() function -- to be included in the next release -- that works
without a hitch with layout()...

I am not posting it here, as i don't know if i am allowed...
