The application is simple to use, but when i tried to save the output file, it complained about spaces in the pathname. E-mail from the developer said that they simply don't allow spaces. Evidently it's too much trouble to support.

I am glad to see this program developed for the Mac, but it's too bad the developers disagree with Apple's interface guidelines that the user is in charge. I can live with interface shortcomings on a free product, but if I'm asked to pay for it... well, no.
