How to turn off wind?

Hi all

I’m working on a simulation of wind blowing the curtains in a window.
When I close the window, the wind still blows.
What do I need to block or turn off the wind?

I tried keyframing, but the on off can’t be keyframed.

Thanks in advance.

You can keyframe the strength value for the wind so drop it down to zero when you close the window.

It worked perfectly!
Thanks Richard. But if I hadn’t watched a tutorial over on Blendercookie I’d have never known that you could hold your mouse over a setting and press I to make a keyframe for that setting.
Blender surprises me every day what you can do with a free program.

Thanks for the quick response.
Also have to keyframe the gravity too, and bring that up so the curtains will lay down.
