That is my doc. When I use documentclass mwrep I got table of contents that is on entire page (even if there are 2 sections in one chapter). But when I use article, table of contents looks fine. How can I get article's look in mwrep?

EDIT:
You are right that chapter won't work with article. What I mean is that I want ToC to look like in article. It would be better to ask how can I get report's look in mwrep.

'mwrep' is supposed to be report class adjusted to Polish typography. How did I get it? I just typed \documentclass[12pt,a4paper]{mwrep} and LEd downloaded it.

EDIT 2:
Look at the difference between mwrep and report here: http://min.us/mdHsA6D and here: http://min.us/mdHsA6D#2

(Note: Your example won't work with the article class because you're using the \chapter command.) Do you want to remove the page break between the table of contents and chapter 1? I wouldn't recommend this, because the ToC should be typeset as an unnumbered chapter. –  lockstep Jul 5 '11 at 19:05
Where did you find the mwrep you are using? –  N.N. Jul 5 '11 at 19:05
@N.N.: It is included in the mwcls package which is part of TeX Live. –  lockstep Jul 5 '11 at 19:07
Add the following to your preamble: \usepackage{etoolbox}\patchcmd{\tableofcontents}{\chapter*}{\section*}{}{}. The ToC should now be formatted as an unnumbered section. Does this answer your question? –  lockstep Jul 5 '11 at 19:19
@lockstep: No, now it looks like it this pdf min.us/mW1st9 . I want it to look like in min.us/mdHsA6D#2 , except I want dot after chapter number (in ToC) like in min.us/mdHsA6D –  Ichibann Jul 5 '11 at 19:24

Simply remove \pagebreak. See \pagebreak vs \newpage for details.
EDIT: To clarify: \chapter internally uses at least one \clearpage, which (for one-column mode) essentially is \newpage plus typesetting left-over floats.
\newpage instead of \pagebreak. So simple... so obvious :D. Thanx :) –  Ichibann Jul 5 '11 at 19:29
