On CentOS 5.7, when open up a vncconfig, a tray icon shows on the taskbar. Hit close or the x button to close the vncconfig doesn't exit the vncconfig, the tray icon is still there. Next time, if I open up another vncconfig rather than clicking the one on taskbar. There will be another vncconfig tray icon added to the taskbar. Except using kill $pid to remove the tray icon, is there any other way to exit the vncconfig process properly? See screenshot below:
