Gerhard-
If you select "Show Perspectives" from the Perspectives menu, a new window will appear. Select "Contexts" in the list on the left, is the "Restore: Focus" box checked?

If that box is unchecked, pressing the Contexts button in the toolbar should leave the view with the same focus it got from Project view. (Checking it is essentially saying "override whatever Project view was doing".)

Does that help?
