I will add that it at least
tries on Windows now with threading turned off, but my last page failed to convert - and that's all I know. The errorlog in Firefox just says it's converting, tells me where the working directory is (true), tells me where it's log is (a lie - there's no log at all). Then it goes away for a L-O-N-G time (> 10 mins, on a single page.) (The xhtml page is 12Kbytes.) And fails.
Hmmm, and on Linux... When I went to try it last night, Firefox stayed up (yay), the page didn't convert (boo.) Brought up the errorlog, nothing interesting, tried it a couple of other pages, failed. Tried it ona selection, worked. (Ahah.) Tried it on
the same pages that earlier failed, they now work. I just hate bugs like that. (Oh, and this was the same machine, no new software, no reboots, nothing.)
