Yes, This is what I am expereancing. The first char of a font are very slow to 
appear, but after that they are quick. This is not just the first char, but 
the first of a font. eg. \alpha\beta etc will be fine until I then use \int 
which then takes a long time etc. Is this becuase i'm using xft, with esstixt 
installed as ttf fonts

I don't understand this. I have esstix installed. They appear as options in 
look-feel::fonts. But I still get this output for each esstix font installed. 

kformula: Font 'esstixthree' not found but 
'ESSTIXThree-12:style=Regular:slant=0:weight=100:pixelsize=16.1751:encoding=iso10646-1 \
:core=False:antialias=True:index=0:outline=True:scalable=True:rgba=0:render=True'.

I get the same output when loading kword. The drop down list has the font 
name, but it isn't displayed using that font. If I select the font the I can 
write with it.

Thanks for the help
Paul
