What? a mighty scroll bar in my Flash Facebook app?!

Solution

First of all, be happy! because the creator of SWFObject (yes, even in official Adobe’s tutorial use SWFObject in their HTML Wrapper for create Facebook application with Flash content) notice about this problem. So they put the solution in their website. You just need to set some CSS style in your HTML file (or external CSS file if necessary). Like below…

html {
  height: 100%;
  overflow: hidden; /* Hides scrollbar in IE */
}

body {
  height: 100%;
  margin: 0;
  padding: 0;
}

#flashcontent {
  height: 100%;
}

Thank you, for SWFObject team! Now your scroll bar will be disappear!
