Intellij 12 + Play 2 + Live Edit doesn't work / flakey

I installed the Play 2 plugin and liveEdit plugin and the jb.crx chrome extension.

When editing scala template files (i.e. main.scala.html), and running in chrome - http://localhost:9000/main, live edit doesn't always work. I've tried with the built in compiler and console play run.

Any tips on getting it working?

Thanks
