I figured after look through the forum that the lack of response was because the developers didn't frequent it. After all, they'd be undercuting their pay-per-support-incident business model.
I really question the ethics of offering a product that is plainly broken for sale as a fully functioning product. In the US, there are consumer protection laws about such things. At the very least, Switch should be removed from NCH's web site. If NCH's site was hosted in the US, I'd be reporting this fact to their upstream ISP and the local AG's consumer fraud department. Oz must not be as strict about such things.
In any case, I've found other tools, more in keeping with the Macintosh shareware approach (buy it and support is free forever). I realize there are other support models, but I'm not really interested in supporting them, especially when both the free and professional products don't work out of the box.
