I don't think it's possible, but it should always use the maximum possible amount of space in your browser's window (?)

Is he opening the swf on a web browser or directly in his computer using flash player? Can you show us a full screen screenshot of what it currently looks like?

A look at the page code would probably help too. Is this a flash page or is it in fact a html page they are trying to embed the swf into? To me, it looks like they are embedding into html and have either not used 100% to fill the div created for the viewer or the div size is incorrect for the page.


However, with more information maybe someone here can help solve this issue.

I'll just summarize all the possibilities here:

1) You're using the area tag incorrectly, restricting the viewer area from your XML

2) It's the container's fault:

* HTML page: Check the CSS and containing elements like Jarredja suggested; try using Firebug (a Firefox addon) or Google Chrome to inspect the tree and find out which element is constraining the size of the viewer window.

* Flash page: You must be loading the viewer using something like a Loader then. I don't know what quirks would need to be ironed out, but the problem would still be in the parent swf.

I had requested a full screen screenshot so I could tell whether you were using a browser and the size of the window when compared to the desktop. Assuming you're in a browser, what happens when you resize the browser window?
