Was looking at the ZX Rainbow page and I see that there's a new version available for download. As ever it's a little tricky to work out just what's changed, especially as it's still touted as the "June" release, tho' the version state is August 12. I think maybe the database thing has been updated, as there's certainly a new WOS database for inclusion in the package.
There's also a new tool on the page, ZX-Paintbrush - as you may have guessed from the name it's a screen$ editor for Windows. It looks ok, with some nice features including conversion to .scr from other formats. At the moment I don't think it will replace my preferred choice of a combination of Bmp2Scr and SevenuP, tho' it's certainly one to watch.
