I have recently installed Linux Mint 10 Julia on my desktop machine last week and there was no problem while using it. But suddenly I noticed that there was no Notification Are on the panel. So I tried to add the same by right clicking on it and then add to panel -> notification area. But still it was not adding it to the panel. Can you guys tell me why it is not adding it? Is there any other settings needs to be done for making this action to take place?
