Sage Software has announced that their Sage MAS 90 and Sage MAS 200 products will be certified for Microsoft Windows VISTA Business Edition only, so if you are thinking of buying a new computer with the new Microsoft VISTA operating system, please take that into account. That does not mean existing or older versions of MAS 90 and MAS 200 will run on VISTA. An announcement will be made in early March regarding the soon to be released version 4.20. If you have questions on this, contact our support department at 678-273-4010 ext 2.
