Robocode Editor/Compiler troubles?

I've been using 1.6.1.4 for a very long time and never had any trouble with the editor. Since I am using 1.7.4.2 that editor has the annoying habit to put some rubbish at the end of the file, so I only use it to compile. Most of the time I use Araxis so I can quickly jump to the places I have been editing. Next to that, I am alas not very active, so an occasional fluke just gets forgotten.
