[TYPO3] RTE-row spaces, fonts?

[Aleksandar Milovac]

Hi everyone,

I'been using T3 v4 on my linux box. I have a question regarding RTE.
When I'm writing something and press enter to go to the next line, space
between two lines looks as if are two empty rows between these two lines.

Something like this:

Bla, bla....

Bla, bla...

, but I want it to look like this:

Bla, bla....
Bla, bla....

What seems to be the problem?

Also, how to change the defaul font size and font family? There are no
these drop down lists in RTE anymore?

Thanks!
