LyX ⇒ Erroneous linebreak

[lechuck]

Hi!

I'm new to LaTeX and LyX... I started writing a Text in LyX using the KOMA-script report class.
But now I stumbled upon a little problem:
One line in a paragraph doesn't seem to break within the boundaries of the justified text. When I change the documentclass back to report, the text looks good again.
I tried to insert \- in some words but that didn't change anything. Also removing the underscores in the last word didn't help.

I created a minimal example and attached it to this thread.

Thanks for your help!

Have you inserted the \- command inside an ERT? I've done so between BO and ARD and I've got a correct break at that point. Perhaps you would like a different break point. But in such a case you should rephrase your text. Likewise, if you would like to use an underscore as the end dash of the line, you could insert after it the command \linebreak (inside ERT).

Hi!

Thanks for your Answer. I used the \linebreak command, because I didn't want the Signalname to be broken apart.
What keeps TeX from breaking the whole word to the next line? Is there a maximum value for the allowable white space between words? And if so, can I edit it in such cases?

You could add to the value "\emergencystretch" to increase the amount of whitespace it'll add to a line.

However, the easiest thing is to put it in a sloppy environment, or use the \sloppy declaration.

\begin{sloppy}
Paragraph with overfull boxes goes here.
\end{sloppy}

Or just:

\sloppy

at the beginning of the document.

I would go with \begin{sloppy}...\end{sloppy}. Putting \sloppy at the beginning of the document isn't such a good idea.

@OP: you should use \linebreak sparingly. At occasions like this, not at all. As frabjous suggested, put an ERT box before that paragraph with problematic line break and type in it: \begin{sloppy}, and after the paragraph put another ERT box and type in it: \end{sloppy}.
