Actually woke up early enough to both feed the cat AND fix a silly bug in StarLines before even leaving for work. Hurrah. It was a silly bug, my base sprite class that I use in the StarLines engine has a function to check if a point is inside it, and I was doing a simple check that only works if the sprite isnt angled. That means it worked most of the time, but not when I was trying to select a moving spaceship.
bah!
Anyway its fixed, and a lot of the old awfull code from 1998 has also gone the way of the dodo.
