Version 8.3.x, which worked in Tiger 10.4.10, was great! But the download link that was emailed with the purchase, and which claims to be valid for "any future releases for Tiger", only leads to the old version. 8.3.x, rather than version 9.0.1 (which purportedly works for Safari 3.0.4 on Tiger). The author does not respond to email queries, it appears (from my experience). I don't expect a lot of hand-holding with a $12 product, but a working download link to the right version would be nice.
