Aptana save css does not update the "preview editor"

Hello I just used Aptana Studio 3.0 3 days ako and loved that it is free and previewing it my html / php code just by saving. While this is not just a very big issue, I would like the Preview Editor tab to refresh when saving CSS code, such as saving html / php codes.

I have css inside my standard web folder folder (mywebsite / css / style.css)

TL; DR:

I would like the "Preview Editor" page to passively refresh when the CSS is saved without actively clicking the refresh button.
