I'm prototyping a Flex app in Fireworks CS4 & have some pop-up dialogs to display. When they show up the background should be blured. I know how to get them to show up, but I can't get a nice blur effect that looks like the one you see in Flash. I've tried a transparent layer with different blur filters, but none look that realistic. Any suggesions?
Can you post a link to an example of what you are trying to create?
Simply go to the Filters section in the Property Inspector panel, select first your object on the canvas (for example, the background), then click the [+] sign in Filters > a small popup menu will open, select Blur > Gaussian blur, and edit the value (0 = zero blur, 4 or more = a lot of blur). Later you can edit or remove the effect, which is good.
I often use Gaussian Blur, especilly if I need to make a bitmap look blurred...
Hopefully this will help you!
