I've updated the current beta with my Windows fixes. There's still some cosmetic infelicities, unfortunate text wrapping and whatnot, but the core functionality is there and the demo patches are all working, save the text/marquee demo which has a hard-coded path to /usr/share/dict/words (if there's a Windows equivalent, changing the path to point to it should fix it). There's also a couple of new externals, including "drop" which enables reading a file's path and contents by dragging and dropping it into the window.
The download url is unchanged from Beta 3. I'll only email the folks who've signed up in the last couple weeks and save the mass spamming for the Beta 4 which will include the Unix fixes and tutorials. As always, if you're interested in testing, lemme know.
