jimbok, this has the makings of a nice solution for my needs.
I installed BACS myself and need to make sure it is not too
complicated for an end-user to use. The BACS icon in the system tray
is the sort of thing which some people (like my girlfriend) has never
really understood even after they used PCs for many years in an
office.
Also the BACS dialog is slightly confusing ("Save" refers to the
report and not the file) and I need to make sure it is suffiently
foolproof.
Now, don't blame me for end-user ignorance. That is the situation I
find. It is not a situation I am responsible for creating! :-)
