Do you switch image stabilisation off when shooting faster than 1/500 handheld?

I posted the question here...

For some reason I cant copy and paste the question into this text box, I just get a compatability error, so I have to use the insert link icon at the top.

I figure most of you shoot at fast shutter speeds on here which is why I was hoping to get your opinion on this...

Thanks,
