Thanks. At times, I have an abominable, terrible habit of chanting to
my girlfriends Sonnets by Shakespeare 8-( It is natural I understand
(almost) all words there. Also, once I had a solid knowledge of Latin.

CF> If a bug wasnt present in a previous version it is just a new bug.

Thank you much for interest in my results, this is nice & refreshing.

Upon reading this you might decide that I am an extremely bad guy, a
real villain the baddy who seeks kicking each & every with a hammer by
head, for no discernible reason ;) Ahh, I am sure that you will be
much disappointed having learnt that actually I'm quite a polite
gentleman who shows discrimination in courtesy & amenity (at least,
many ladies reported me so :)

But it seems that the time has come to kill once & for good a strange
fallacy the long-liver often told me and by unknown reason advertised
by mathematicians & programmers & student users in sci.math.symbolic &
comp.soft-sys.math.maple - just the same you had produced. Even the
most serious & competent researchers (who aren't professional software
testers) by a reason I cannot realize, keep using this invalid
terminology.

Okay, for starters, couldn't you please consider an idea of visiting
my experience here http://www.cas-testing.org/index.php?list=3 ?

Also, why don't consider reading opinions about quality & scope of my
work produced by experts in the field of computer algebra systems
placed here http://www.cas-testing.org/index.php?list=7 ?

About those mysterious "regression bugs". Here you are

http://www.e-promag.com/epnewsletters/index.cfm?fuseaction=ShowNewsletterItem&ID=4694

A regression bug is one where a feature worked before, but a release
or update broke that feature so that it doesn't work or doesn't work
as expected.

http://www.mcse.ms/archive89-2004-1-280186.html

A "regression bug" is any bug that has been fixed, but that the fix
itself is either not correct (as in this case) or has caused some
other bug to occur.

http://www-10.lotus.com/ldd/r5fixlist.nsf/0/a2bc10f5bc66eec085256cb80055a8b1?OpenDocument

A regression bug is a bug that was introduced in a MR or MU that did
not exist in previous releases of that code stream. For example, a bug
that appears in R5.0.9 but did not exist in R5.0.8 is a regression
bug.

http://m1.mny.co.za/help/readme.nsf/0/4bcbe10112e1e01785256a07004a5e08?OpenDocument

A regression bug is a bug which was introduced in a QMR or QMU and did
not exist in previous releases of that code stream. For example, a bug
that appears in R5.0.4 but did not exist in R5.0.3 is a regression.

regression bug in pywintypes SECURITY_ATTRIBUTES?

scroll bug

Why it is so important for me to clarify this, and, for many readers
of sci.math.symbolic & comp.soft-sys.math.maple, to learn this?

Because I am going to make a historic speech that Maple 9.5.1 has been
enweaved with, at least, thousands regression bugs - to speak nothing
about even worse problems. Now this's significant in its consequences.

But I shall not rob you of the pleasure of enjoying my upcoming
results being published soon ;)
