I can't see who is speaking with the Ventrilo overlay

Hey guys, I'm kinda new with ventrilo, but I feel like I did everything right...

I managed to get the overlay working by running planetside 2 in window mode, but the overlay window is useless to me. I hear people talk but it does not display ANY information about it.
It's just a static useless box... I've tried uninstalling the 64bit version and install the 32 bit version like it was suggested in a PS2 thread. But it still does not work.

Did I miss something ? thanks in advance.

OK I figured it out, sorry for the bother... apparently I need to tick the VISTA compatibility box.... (yes because i'm totally using vista... not) Way to update your client ventrilo...

Anyway it's working now.
