I've been experimenting with the pseudo full screen script available in the AVSIM library so that I can run in windowed mode but hide the annoying bars. The problem is that it rarely works in FSX (nothing happens when I press the win-f11 key combo).  It works fine in all other programs I've tried, just not FSX.  Any ideas? I'm running Windows 8.

I use AutoHotKey ... it works just fine.

I figured it out. Have to run the script as an administrator in windows 8. Works fine now.
