Enabling Compiz Disables Windows Title Bar - Why?

Ubuntu 11.04 here.

I have Compiz Fusion Icon. When I choose compiz, to benefit from the effects, my windows title bar disappear.

How can I make it appear, and preserve the effects ?

Note:

If I go to Compiz Fusion Icon > Select Windows Manager > Metacity
I got the tittle bar but not the effects.

If I go to Compiz Fusion Icon > Select Windows Manager > Compiz
I got the effects but not the title bar.

Thanks

Solution 1:

Go to:

CompizConfig Settings Manager > Effects

Make SURE Window Decoration is checked.
