Funny you mention that. When editing a style and I click the "Update Preview Area" nothing changes. I have to save the style, then look at my board in another open window to see the change.

I'm on IE7. I wonder if it's related to my problem here:

Maybe I should open a support ticket.

I'll get there with the style. Just need to spend more time playing in Control Panel.
