System Tray Problem
 

When I close my limewire, it used to minimize (showing an icon) in the sustem tray, now, I didnt change any settings, controled in the options, and it's still set OK (so that it should minimize in ST), but now, when I close limewire, it doesnt show in the system tray! so I need to restart it, but it did not shut down so when I start it, it starts two limewire's, the first that was already activated, and a new one, so it slows down my computer and it's annoying :( anyone knows why??

any help would be greatly appreciated!!!!!
