Hi Anton, I was testing this just now with the latest Texo build and I can reproduce it also on an eclipse install where I removed the Texo plugins. It can be reproduced in a standard Java project, but if I use a plugin project it didn't happen. Can you try it for me on a clean eclipse install and then with a standard Java project and plugin project? gr. Martin
No reaction for a while, closing the issue, please re-open when reproducable. gr. Martin
