If you attempt to export a project to MPX format with more than one resource, and try to open it (in Project 2003 at least) it just gives you an error and refuses to open the file.

It's pretty easy to reproduce:

-Make a new project
-Go to the Resources section, add two resources
-Export as MPX
-Try to open in Project 2003 = error and file cannot open

OmniPlan is coming along quite well. As soon as export is reliable, I'll be able to move to it as my main project management system.

I just did this in our latest alpha version and it looks like the problem is gone. Keep an eye out for Beta 9. :)
