I noticed in your code there is no IMPLEMENT_SAVERESTORE after the
TYPEDESCRIPTION block. Did you just not put the code in the mail or is it
not there at all? I'm guessing that without using IMPLEMENT_SAVERESTORE,
the variables won't be saved (it is called implement, after all). The
code still compiles fine in the absence of IMPLEMENT_SAVERESTORE though.
