The font default definition for what??

>Hi All,

>I need your help: in FoxPro 8 (and 6 also) the font default definition (under Properties) was Ariel Bold. But the outcome is not simply a letter whish is a bit thicker - the outcome is a chunk of black which is hardly readable. Highlighting, in general, is uncontrollable! This happens in FoxPro itself before implementation on our software!
