I'll look into this... Basically I cut this code out of WNSTORM where it works correctly. Since I wrote this very quickly, you can tell I did minimal debugging on it... argv[2][0] should be '-' argv[2][1] should be 'R' argv[2][2] should be 'F' argv[2][3] should be ':' argv[2][4]... should be the random file. Try it without the '-' infront of RF: and see if it makes a difference. Meanwhile I'll check this out...
