Great answers, Leo.

This provides the basis for further research.  BTW, the path was 
originally blank in the ini, with no GC occurring.  Next, I entered a 
path in the ini, using the path where I found the files: 
C:\WINDOWS\Temp. Still no GC.

I will try your suggested experiments.

Stay tuned....
