How to configure Eclipse to always launch the last run configuration, not the current file?

Question

Back in 2008, around version 3.4, Eclipse changed the default behavior of the Run button to attempt to launch the file with focus, rather than launching the same run configuration that was run the last time. How do I get the old behavior back?

Answer 1

According to a post on Loving Software Blog, you change the following preference:

Run/Debug -> Launching panel; Launch Operation section; change radio button to "Always launch the previously launched application".

I've verified that this works in Indigo, the current version.
