Intellij not compiling before test for one project

Hello paul,

Please make sure that the "Make before run" option is enabled for the run
configuration of your unit test.

Had a project working fine in IntelliJ 7.0.5, opened in Intellij 9.0
and now no longer recompiles changed code before running a unit test.
But I dont know if Intellij 9 was actually the issue because it fails
in 7.0.5 now as well, and I have another project working fine in 9.0.
I've looked through the preferences but cannot find any options about
autocompiling

I went to try that, but when I reopened the project it crashed, and subsequently it wasn't recognising UTF=8 files properly, so I deleted the project and recreated and now everything is working
