When I am closing the Xchat it is asking for to "Quit","Cancel" or "Minimize to Tray". If I am selecting "Minimizing to tray" then the Xchat is disappearing and I am not able to see the application again.
I have checked process list and it is there in running state. Normally in earlier version of Ubuntu it will show a Xchat icon in the top panel bar.
I have not added the Xchat as sticky icon in my application panel. I hope there must be some work around or setting for it.
