Note 1.  Summary of Significant Accounting Policies

Revenue Recognition, page F-10

1. Disclosure on page 7 indicates that you provide technical
support
to your customers.  Describe the nature and material terms of your
technical support offering, including whether it is included with
the
cost of your products and services or sold separately, whether it
is
renewable and your policy for recognizing revenue for this
service.
Tell us what consideration you gave to including this information
in
your policy disclosures.

2. Tell us whether all software packages sold by you require
modification or customization and whether all such arrangements
are
accounted for on a percentage of completion basis. If you sell

customization
tell us the authoritative literature you apply in accounting for

sale of these packages and your revenue recognition policy.

Form 10-Q for the Fiscal Quarter Ended June 30, 2005

Item 4.  Controls and Procedures, page 18

3. We note your disclosure that your "management, under the
supervision of the Chief Executive Officer and Chief Financial
Officer, performed an evaluation of the effectiveness of the
design
and operation of the Company`s disclosure controls and procedures
as
of the end of the period covered by this quarterly report" and
that
"the CEO and CFO concluded that the Company`s disclosure controls
and
procedures are effective."  Clarify, if true, that your officers
concluded that your disclosure controls and procedures are
designed,
and are effective, to give reasonable assurance that the
information
required to be disclosed by the Company in reports that it files
under the Exchange Act is recorded, processed, summarized and
reported within the time periods specified in the rules and forms
of
the SEC.  In addition, tell us whether your officers concluded
that
your disclosure controls and procedures are also effective to
ensure
that information required to be disclosed in the reports that you
file or submit under the Exchange Act is accumulated and
communicated
to your management, including your chief executive officer and
chief
financial officer, to allow timely decisions regarding required
disclosure.  We refer you to Exchange Act Rule 13a-15(e).  Tell us
what consideration you gave to including this information in your
disclosure under Item 4.

	 We urge all persons who are responsible for the accuracy and
adequacy of the disclosure in the filing reviewed by the staff to

certain that they have provided all information investors require

are
responsible for the accuracy and adequacy of the disclosures they

provide,
in writing, a statement from the company acknowledging that:

* the company is responsible for the adequacy and accuracy of the
disclosure in the filing;

* staff comments or changes to disclosure in response to staff
comments do not foreclose the Commission from taking any action

respect to the filing; and

* the company may not assert staff comments as a defense in any
proceeding initiated by the Commission or any person under the
federal securities laws of the United States.

      In addition, please be advised that the Division of
Enforcement
has access to all information you provide to the staff of the
Division of Corporation Finance in our review of your filing or in
