Hi Mark,

Actually, of the three examples at the base of the OpenCL section 
(OpenCLLink/guide/OpenCLLink), this was the only example that did work 
under Win7 x64 with a Radeon Mobility 4570.

The first two print a Manipulate-like box with "$Failed" in the area 
where the Graphics are supposed to live.  The error I get is 
"OpenCLFunction::invgrdsz: OpenCLLink grid size is invalid. >>".

I don't know what it means either.
