True, Kodak Rapid Selenium Toner does contain fixer. But a dilution
of 1:100 is a homeopathic dosis and probably (?) has much less
bleaching power than the final hypo bath. True too, however, that
selenium even at 1:100 will bleach the print if bathed too long (1 or
2 minutes was the maximum time for me, if I recall correctly). (This
is to say, Judy, that I doubt that home-made selenium toner without
hypo would not bleach the print -- I doubt but don't know.)

Of course, times always depend on the strength of the solution. In
my experience VDBs need both a good first wash (at least 5 min) and a
good fix. I fix 5 min in hypo 5%. At the beginning I yielded to the
temptation to fix for less than 5 minutes and I regretted that very
much when I looked at the prints a couple of months later.

As to image colour, I noticed that VDBs come in a wide range of
colours. One factor that seems to influence colour more than
anything else is the humidity of the paper. Apart from this selenium
does shift colour towards cooler shades of brown.

To sum up my experience with VDB: it is an easy and versatile
process, particularly good for beginners in ALT photography, capable
of yielding results such that you may not want to look any further.
But make sure that you wash & fix & wash carefully!
