Ross, my results are the same as yours. (Nota Bene 7.0b, Win XP Pro.) James At 04:36 pm 10.11.05, you wrote:Everyone, I am still having problems, i think, with uniqcomp.pm. When i try and use it, it gets into a hardloop and puts repeated copies of NMIN until i stop the program. For someone who is having success, could you please try the program on the sample text files i've included? I think this could be a really great program, but i seem to be having problems. Thanks Russ
