It's been a tough couple of weeks for the Tinderbox Windows project. Lots of niggling problems in the windowing system, all touching on the HypertextView class, piled up. And then, perplexingly, we started getting a really nasty crash when quitting.
It turns out that Tinderbox for Windows was tearing down the window structure and deleting the parts of its data structure in a different sequence from the Macintosh version, and this led to subtle memory reclamation disasters.
And, after everyone, Windows XP eagerly offered to tell Microsoft all about it. Sigh.
All better now. Thanks for asking.
