Satscape for Java is now at the BETA test stage of development. This means all the main parts of the program are in place, but theres still several things that need adding, and probably several bugs to fix. My own testing has shown that it seems to work well in both Windows and Linux, and I've heard it works well on an apple Mac too, if you can get hold of Java 6 for Mac. Ive also put a new feature on the web site called 'bug tracker' where you can view and add bug reports, see what bugs or features I'm currently working on, and be kept up to date on a particular bug or feature, so check it out, you'll find the link on the top-left of most of the pages.
