wbar back-grounding problem

Hello,

I have placed wbar at my .icewm/startup so that it can start automatically and back grounding it. 

`````````
(wbar  -above-desk  -nofont -pos top  -zoomf 1.3 -isize 15  -idist 8
-jumpf 0.9  -nanim 2  -balfa 0) &

````````````````````

The above configuration is in a single line. Problem is wbar though starts fine but not back grounded properly. As a result it is no more possible to logout from the xsession. After pressing logout all the applications are stopped and terminated but the icewm is still stick as it is. If I comment the above configuration then no problem to logout from X. It surely indicates that wbar is not been back grounded. Could any one suggest any work around to fix it ?

Thanks
