If you’re one of the early adopters of Excel 2007, then FlowBreeze is ready for you. The flow chart add-in for Excel is now Excel 2007 compatible. Excel now has a Ribbon replacing the classic menus and toolbars, but the FlowBreeze toolbar is still accessible under the Add-Ins tab of the Ribbon.
More info (and pictures!) will be posted soon.
(P.S. Vista compatibility is still in process.)
