font size
 

i've a problem with font size, it's fine anywhere but in the software menus
Like when i want to open a file with xmms, the toolbox has very tiny fonts i can barely read what's written
How can i change that?

in red hat i can adjust my system wide font setting by going to Preference->Font. try find something similar in mandrake and adjust the default settings.

i tried it, everything is at 12 or 11 size but that didn't had any impact on the menu

hmmm.. have u try changing the font? look at other settings like font rendering or resolution (dots per inch).

i tried to play with the fonts but without a result

might be something wrong with u X font server settings. i'm sorry but that is beyond me. try google on that subject.
