[xubuntu-users] The font size of the diagram content is too small!

[Edwin Y.X. Zeng]

Dear Team.

The xubuntu 7.04 was installed in my IBM T40. It works fine always until
one day, the default of system fonts-size was set as below(in the "user
interface" ):
	serif	regular	12
I am certain that the fonts is larg enough, and the screen
resolution(1024*768) too. also the mostly fonts-size is normal such as
diagram menu,toolbar etc, except some diagram pannel,such as the mail
contents in evolution, webpage contents in Firefox, and some program
warn/error message. the dirty size is very small, just like only 8 maybe
smaller.  I set the default font style and size to anyother, but the
symptom is same also.

How and where can I set them comformable?
