bug of the day

[forgotten_aria]

In evolution if I write 'st' it only shows the 't'. If I deleted the 't', the 's' shows up again. If I cut and past the word from evolution to another window the st are there. The spell checker thinks the st is there. If I type 'sst' it looks like 'st' on the screen, but of course it is actually 'sst'

I can't figure out how to change the default font.
