When I click on the visual effects option in the Tools menu of FSX, nothing happens. How do you get to use the special effects SDK? I have no trouble with the traffic toolbox and object palcement options, but can't get the effects option to work. I have SP2 installed and the SP2 version of the SDK.

Well, I figured out my problem. I normaly play in full screen and when you click on the FX tool, it opens in it's own window underneath the FSX screen. When I changed to windowed mode, the FX tool window opened on top of the FSX window. All is well now. :)
