Modal window?

Hi all,

Just a quick question, I have seen allot of sites out there that have a cool little feature that I just cant seem to get a hold of and hope someone can help.

I what would like to get is [SIZE=-1]when someone clicks on a button or movie clip a full screen pops up, one similar to the [/SIZE][SIZE=-1]Lightbox image effect seen on allot of sites. I know that there is a Flash version of [/SIZE][SIZE=-1]Lightbox one this site but I cant seem to just get the effect of a full screen window opening.

Once the window is open I dont want the buttons or content in the background to be visible.

Thanks allot and hope someone can help!! :wink:
