Some of my toolbar Icons have disappeared...!!!

[Doggett]

Where have they gone?
I'm using Vista AND IS THIS MEANT TO HAPPEN !!!!
How do I get them back, I had this margin thing with a clock and everything and now it's all disappeared.All the icons in the bottom left hand corner are still there but the ones in the right are all but gone. The only ones I have left are my security programme and a green MySpace bubble

Will I ever see them again.

One of them still owes me money!!!!!

Have you restarted your computer yet?

Have you restarted your computer yet?

You mean, um, switch it off and on again.

...

no.

Perhaps I should've tried that instead of panicking at the slightest thing like I normally do.
