I have looking at and have installed 'aspell'. Everything you have said is right as far as I can tell. I even went back to my Linux box and lo-behold, the spell utility is just a link to 'aspell -l --mode=none'(where Test::Spelling works just fine).

However, I tried to use 'aspell -l' on Windows and it is just sits there. Evidently there seems to be some sort of incompability between the *NIX implementation and the Windows implementation how it handles getting input from STDIN.

Update: I found out that version 0.10 has this bug. This also happened to be the version that I had installed by ppm. I went installed a more current version off of cpan and it was fixed!

Thanks for pointing me in the right direction!
