OpenGate Software has been actively working with MS Access 2010 since late 2008, including visits to Microsoft's campus in Redmond, WA to review and work with early "pre-alpha" drops of the release. We have tested our products in Access 2010, and will continue to do so to ensure compatibility with Access 2010 when Microsoft releases Office 2010 to market in mid-2010.
You can purchase an OpenGate Software Microsoft Access product now, knowing it can be converted to Access 2010 when the product becomes available.
