and the problem also with many programs like (skype tunngle u torrent )
so if i want to see the programs i need to go to the shortcut in the start menu
why that !!!!! please help me

Not all programs put themselves in the notification area. You could pin them to the taskbar if you use them that much.

I have noticed that sometimes the Nod32 system tray icon fails to load for some unknown reason. The program is active and working but the icon just fails to load every now and then for me. And that happens with Comodo Firewall too sometimes. When that happens, I simply log off and back on again and 99 times out a 100, the missing icons are back where they belong in the system tray.

Why these errors occur, I do not know.

that's right but i want to fix that problem

but that happens with Windows 7 only
maybe the windows professor can show us the way to solve it

Good luck! Please consider posting back if you find the solution.
