Spark Process don't closes

Hello, i’m implementing Openfire server in my work, but we found some issues with the spark :

  • When the Spark window closes ( with the X button of the window or in the Menu Spark “Close”), the spark process still work in background, and the icon don’t go to the clock bar.

We uses Ubuntu 9.04, and we test with the 8.10 too, and the same hapens.

Someone know how i can fix this ?

Thanks.
