Compass doesn't output vendor specific declaration in Scout
I've started to use Scout (Windows version on WIN7) for a new project and although it's supposed to contain Compass, the generated css file never contains any vendor-specific declaration whatever I write into the scss file. For example, only border-radius can be found in the output. No trace of -webkit-border-radius etc.
I've been searching the web for any info about it but couldn't find anything.
