How to show context menu when right-click released? [closed]

I'm using Ubuntu 10.04.

When I right-click, menu popup too quickly, and the first menu item is clicked.

If I right-click in desktop, it create a new folder sometime.

If I right-click in terminal, it open a new terminal sometime.

...

Is there some way to delay context menu?

Or how can I offset context menu a little bit pixels to the right-bottom direction? (like firefox)

Or how can I config Gnome to popup menu when right-mouse released? (like windows xp)

This is a known bug:

• Bug report in Launchpad - unfortunately only a wishlist bug. :-(
• Upstream bug report - more information, no consensus reached yet (means: wait or contribute).
