I need to perform reads without using any caching. I have the line "invalidate=1" in my job file, however it is still using the cache. I am running Windows 7 32-bit. Is the "invalidate" command supposed to be functional on Windows? If so, what am I doing wrong? That aside, what a great utility this is - thankyou!!
