Selecting multiple projects in Aperture

I am trying to create a new library from a subset of projects from my full AP library. Since I have >100 projects, when I select the first few, I need to scroll down to select more using command +click. When I click on a project further down the screen, however, AP automatically scrolls back to the beginning (my first selected project). Then I need to scroll down again and find the next project, select it, and it sends me to the beginning, so I have to repeat again with the next. It's extremely annoying. Has anyone else experienced that? Any possible solution? Thanks.

 

That is exactly where I select them - in the Project view. As I said I have >100 projects so I need to scroll down even in the project view.

 

Thanks! I think this works if you sort by oldest first.
