I'm using the Ubuntu 11.4 SO and my keyboard is set for USA Alternative Internetional so all it's work out of the Zimbra ( for exemplo in my notepad or my text editor ) but when I go inside of Zibra to Write a email my cedilla key doesn't work!

how can I solve this problem? where I can change my preferences Keyboard inside of the Zimbra?

any tip it's welcome.
