Not to be confused with Project: VISION is another project management tool with almost the same name. This one however is a Windows program. It's shareware and sells for about $80. A typical screen looks like this.
What is not obvious from a single screen shot is the unusual arrangement of the tool bar across the top of the screen. The icons have some non-standard meanings. Without tool-notes, you have to look at the bottom of the screen to see what you're about to do. There is no way to zoom the screen to a particular size. The files take an exceptionally long time to load into the program and the scroll bars at the side and bottom move the image around the screen either agonizingly slow or blazingly fast.
The program does support all the typical PM concepts. It uses a conceptual model of a Critical Path Method chart with the critical activities in red and non-critical ones in blue. You can change the dates and times that surround each event, but there's no way to tell whether the dates represent Early Starts, Late Starts, Early Finish, Late Finish, etc.
All in all, I'd call this a noble attempt at providing a PM tool but it still needs some polishing before I'd recommend it.
