Hello,

I've just updated from cvs and I'm trying it.


I note that the  Typeface that is selected in a new  Family is that of
same row than  in the previous. This is not  good enough. For example,
in Efont Serif, I got Normal, Italic, Bold and BoldItalic. If I select
Bold and then click on  Courier, where I have Normal, Italic, Oblique,
Bold,  BoldOblique,  BoldItalic, then  it's  Courier  Oblique that  is
selected, not Courier Bold as expected.

Note  also that  the  preview box  shoes  : Courier  NoFace 12PT,  not
Courier  Oblique! Same if  the previous  selected Typeface  is Normal,
selecting another Family puts NoFace in the preview box.



I've  got  some  strange  fonts  behavior (for  example  there's  four
Tektronix Normal), so I'll rebuild the caches and check again later.
