Ok, I can confirm that the error I am experiencing is because of the max length of the text area. If I comment the line with the max length out, I do have a line break. Problem is: The version of the program is already in the end of the testing stage and I will make some people very unhappy if I change the coolite.dlls and they can start testing all over again.
Is there some way I can fix this without updating from svn? I will of course do that for the next version of the programm.
