[K12OSN] Centos5, FF3 and text overlapping

[Mella]

Hello!

I try to understand, why text is overlapping. In screen all seems almost 
OK. In print preview most letters are too close. Some letters are 
overlapping.

There is no problems with Ubuntu 8 and windows xp/vista. Only Centos 5 
with Firefox 3. FF2 works ok.
Also there is problem with Chrome and Vista.

Any ideas?
