Problem with default rich editor font.

[slangmgh]

I set the default rich editor font to Tohama(Option/Editor), and new text item, the font shows Tohama, but when I type some english text, the font turn into "Arial", in fact, everytime I type englist text, the text font is "Arial" no matter how I change the font.

I use xp, and I have tried every version of the riched20.dll (2003,2007,2010), same result.
