Joel Canfield (and Ian and maybe a few others) asked:

I've used them on some 'search' form 'front-end's where I'm gathering
end user
parameters for running a report and offering a dozen different search
criteria.
These were cases where I didn't want to go with automagically resetting
the form
to default on entry since I wanted to allow the user to be able to go
back and review the
input parameters they entered after execution. (That way they can see
whether they
didn't get any results because they mistyped a part number or
something.)
Sometimes I'll write a routine to cycle through the possible search
selections; see if
the entered value has length > 0 and determine if I need to instantiate
a new 'where'
clause or tear one down that isn't being used. .... Sometimes I'll just
add an easy
'reset' button to the form to clear out the text fields and associated
where clauses
and be done with it.
Sometimes it comes down to how much time you have to work on the form.
Sometimes it comes
down to what your users might prefer. Sometimes it comes down to what
the technology
will or will not let you do. [Not every technology gives you this much
flexibility.]
