Fscommands NOT working

Okay, I’m making a CD-Rom and for some reason I can’t seem to figure out why the fscommands don’t work.

My code is:
fscommand(“fullscreen”, “false”);
fscommand(“allowscale”, “false”);
fscommand(“showmenu”, “false”);

and on a button, I have:
this.onPress=function(){
fscommand(“exec”, “application.pdf”);

For some reason, nothings working. I can still resize the window, I can still make it full screen, the “exec” command isn’t actually doing anything at all. On a positive note, the menu isn’t showing, so that’s a plus.

Anyone know what the problem is? I can’t seem to find anything via my google search so I thought i’d try here. Let me know. Thanks.
