Is it possible to clear the 'program installed' icons at the top notification bar? When you perform an update of an installed program, the top notification bar displays a 'downloading' icon.

When it is downloaded, it displays a 'successfully updated' icon.

Is there a way to clear these 'successfully updated' icons?

I found no other way than to pull down the notification bar, and click the installed notification messages, but this always starts the updated program.

I was just wondering if you can clear these icons without having to start the program.

A minor thing, I know, but once I get a question like that in my head...
Towards the top of your notification bar there should be a Clear button. Click this to clear your notifications (this will clear all pending notifications, not just application installed/updated ones).
