V1.6.8 running great on one computer, but cannot initialize GPU's on the other.  Log says Error CL_BUILD_PROGRAM_FAILURE when calling clBuildProgram [ctx->Program] for DeviceID 0 (Thread 0).  I've done everything I can think to make certain the Config file has the correct syntax, to include changes like the post directly above.  What else can cause this problem?  V1.6.7 runs fine on same computer.

Solution found if anyone is interested:  Can't use build 1803.  Roll it back or reinstall.
