Crossword Compiler is a Windows application. The last time I tried running it on Linux, a few years back, it didn't work. But today it works. Kinda. Far enough to fill in a grid with words, which is what I need. (If I ask it to lay out a page with a grid and clues, it tries to lay out an infinite number of blank pages. But that's OK, I can lay out a page by hand. But I can't fill in a grid by hand. Not a dense grid, anyhow. So it runs well enough, hooray.) I don't know whether that means that WINE (the standard Windows emulator for Linux) got better meanwhile or whether Crossword Compiler does fewer tricky-to-emulate Windowsy things. I just know I'm pretty stoked to be able to run this piece of software.
