Another problem with scim configuration.

Hi, Thank you for the advices, I've just installed all the binary of United linux an now I can run scim under a terminal (rxvt). I'm studying chinese so I'm not very comfortable with all the options written in chinese in the dialogue box... so when I start scim all seems ok: with ctrl-space I can activate the small window in which I can see all the characters that corresponding to the pinyin written but when I try to select one of them (with space or with the corresponding number) I can't see the character on the terminal.(all disappear) Another question: there's an option to enlarge the character in the small window with characters that corresponding to the pinyin written? Thank you very much! Giulio F.
