That is how i envisioned the xchat system to work, however this is not what i have found. So far, i cannot locate any proof to such extent as It very much reminds me of a bad dream, how the boxes explode into the window the second someone whispers you... That would be extremely annoying.
I may just be paranoid. In fact I probably am. =)
Things like this can destroy the playability and I just want my Precious D3 to be all-i-ever wanted.
