Remove gaps between tracks in Audio CDs k3b

[Eithel]

Hi guys, I'm searching a simple way to remove the gaps between tracks in Audio CDs in the k3b program. I've found, on the net, some guides that says:
"Should you want to change the default two second silent gap between tracks, right click on a track
and select Properties. In the Audio Track Properties window that opens, click on Options and raise or lower
the Pregap value"

But in my Audio Track Properties window there is a Post gap option but i don't have any Pregap value. I tried to set Postgap value to 0, and burn cd in disk-at-once (DAO) mode, but my Cd has always two seconds silent gap !

Can someone help me to remove this gap ??
It's very annoying on live tracks
