OpenProj- How to change start date

[hringm]

How do you change the start date on a project in the program OpenProj?

My department is supposed to start using OpenProj for our projects. My boss made a template that shows the standard tasks and time durations for our projects.

On the template, he put the start date for the entire project as 1/3/11, since it's just a template for us to work from. I want to change the date back to 3/1/10, since that's when my project started, but I can't figure out how to do that. If I double click the start date, then the "Task Information - 1" box comes up, I can change the date on the little calendar back to March 1, 2010, then a little box comes up and says "May this task start before the project start?" and I click "OK", and then the date immediately goes back to 1/3/11.

I also went to Project drop down menu, chose Projects, and changed the date there. It let me change the date to 3/1/10 there, but that didn't seem to affect anything else.

So, does anyone know how to change the start date in OpenProj? Thanks for your help.

"It let me change the date to 3/1/10 there, but that didn't seem to affect anything else." based on what, exactly? Unless you then entered a task on the desired start date, and the program complained...

The example that my boss made is a Gantt chart, showing when the project tasks start and end. On the example, the overall project starts on 1/3/11.

I meant it didn't seem to affect anything else, in that I still can't change the start date for the project on the Gantt chart. Under the Project Menu, I changed the start date to 3/1/10. But when I click on the start date for the project in the Gantt chart to change it to 3/1/10, it won't change.

I'm guessing there's something obvious I'm missing, but I can't get the Gantt chart to change to the days I want it to for my project. I realize that I could just start a totally new file and enter each task and days by hand, but it would be a lot quicker and less likely for mistakes if I could use the example I already had and just change the start date in that.
