Css file isn't updated when scss was changed

[mat-b-]

While developing the store, I disabled all caches and indexes.

Before Sass module, this resulted in quick workflow:

• change css
• refresh the browser to see the result

But with Sass module, changing scss doesn't result in css file refresh.
I have to manually flush Magento cache or delete css file.

How can I make it update for every change?

Magento 1.9.1

If you disable the SASS cache this should mean it compiles each time you refresh the page - it is slow though!
