Alt+e (Polish "ę") keybord shortcut doesn't work

Hi,

I'm currently using demo version of Trados Studio. I operate in Polish and I have a problem with typing Polish "ę" letter while creating records in term base. "ę" is coded by alt+e keyboard shortcut. It works fine while normally translating but fails in the term base editor window. The consultant which advises me said, he unsuccessfully tried to solve this problem and that it was probably a kind of bug. Anybody knows how to solve it?
