@Richard, you know the old saying? "Even a blind pig will find ..........."

In truth my memory sucks. Something just struck a cord here. I think it was the Waterfall name.

The search feature is quite handy for this stuff. You will find many many results with people who have gopro's. I tried to "detect" the error, but it happens outside of the ARC environment. It's sad that gopro has done nothing to resolve it - even though it's affecting all of their customers from using software that uses webcams.

thank you all. removing ipp stuff seems to have fixed the problem
