Hey Charles,
About stability and memleaks: aside from the numerous leaks one can easily get from IE, I do not believe Scripty suffers from memory leak issues (or if it does, they're too tiny for me to experience in Scripty-intensive apps I keep open for weeks on end and use every other minute).
Thomas and I would sure be interested in getting details and reproduceable use cases, especially if they come with unit-tested patches :-)
It would also be interesting to know which version of Scripty the GWT team was alluding to. Plus, Scripty 2.0's effects engine was rewritten from the ground up and is way different internally than its 1.8 counterpart, so if an issue existed, it may well be gone in the next release.
Regarding the book: AFAIK, it's available wherever books are sold. I know Barnes & Nobles has it (and is often sold out on it, too, even the huge NYC one!), and the book certainly sells through regular retail channels.
I wish Amazon would publish reviews in a timely fashion. I've been getting reports of a dozen reviewers who can't understand why their (glowing) reviews don't show up on the book's page� If you want to peruse, you can always look at the couple excerpts on
the book's page at Prag Prog.
Cheers,
