After reading John's post and then re-reading yours it is clear that I
misunderstood the question - two forms accessing the same table is no big
deal. I often have a list form and then a detail form for a single table.
Granted, as John cautions you don't want to create a situation where both
forms might be open and accessing the same record simultaneously. When I use
a list form and a detail form I generally make the list form read only and
require that all edits go through the detail form.
Often a listbox serves just as well as the list form though in a continuous
form you have some native functionality which is nice (filter by
selection,filter by form, simple sorts, etc).
