However, there is a strange issue when you are working with multiple
projects open.
1. Bring project1 to the front. Press ⇧⌘F and search in that project.
The search window will have a list of matches in project1.
2. Bring project2 to the front (perhaps to make a quick edit).
3. Press ⇧⌘F to bring the search window to the front again. Click on one
of the matches that are still in the search window from before.
4. The file with the match is opened as a tab in project2 rather than
project1.

This has now been fixed in 2.0-rc.22 :)
