I really hope Livingston's development has a bugs' database and
it's not just for documentation purposes; and I really hope
customers will have access to it or part of it someday.
I think this would reduce traffic on the list by a factor of 2 at least,
and save Livingston additional manpower in tech support.
Not that the "bug tool" will *solve* the problems magically,
but at least we will know the problems has been noticed, there's
a work currently going on, possible workarounds are...
Or am I asking too much and Livingston will never get even
slightly near the level Cisco provides support at? Even if
payed for?
