Console reporting OpenCL errors - Renders are fine though

Hi,

I have an issue where my rendering from Fusion seems to work fine, although now and again it hangs for about 8 seconds (mouse, hanging too) and then continues like it's all ok.

Also for every frame rendered I get the following message in the Console:

OpenCL clCreateKernel: CL_INVALID_PROGRAM_EXECUTABLE

I suspect it might be due to a 'sick' GPU. I have a Quadro 5100M btw.

Anybody know what this could be about?

Thanks,

Marc
