Gantt-chart zoom doesn't go all the way out

Hi, I thought I'd ask for help here.

When using Gantt view, I'd like to be able to zoom out until I have my entire project in the viewing area. However, even if I zoom all the way out, a fair bit of my 4-year project is hidden to the right so I have to scroll to view items there.

I know I can print the entire range to a separate file, but I'd like to be able to see the entire project while working on it.

The attached picture file shows the problem

Is there any way I can do this?

Thanks in advance,

Erik Høines
