   Yes, that is correct.  When you checkout a particular version, that 
will be noted in CVS's local housekeeping files (the ones in the CVS 
directory).  This is known as a "sticky tag."  You can discard this 
information and go back to working on the head of the source tree by 
using "cvs update -A".

   I was bitten on the a**e by that one too when I was a CVS newbie.  :-)
