Ventrilo PTT

I installed ventrilo through wine. It works perfect but i have a problem with push-to-talk function. It works only if ventrilo window is focused so i’d like to ask u if is there any way to forward(or something like that) some key("`" GRAVE for ex.) to ventrilo window?

I was looking for in google and found ventriloctrl but it doesn’t work for me.

OS: OpenSUSE 11.2
Wine: 1.1.36
Ventrilo ver: 2.1.4
