Compass sees changes to scss, overwrites css but no changes are made

I have ruby, compass, and sass installed in my environment. I can successfully run:

compass watch

And when I make updates to the scss file, I see the following:

>>> Change detected at 19:34:38 to: scss/_profile.scss
overwrite site/css/style.css

However, if I add a class style to the scss, I don't see the change in style.css. I'm not experiencing any errors, but it just doesn't seem to ever update the css.

Here are my environment details:

• Windows Server 2012 (64 bit)


• Ruby 2.1.5p273


• Compass 0.12.7


• Sass 3.2.19

Any ideas?

Thanks in advance, Kevin
