Not reactive to mouse navigation buttons

What version of Ubuntu/software-center do you use?

I got used for back and forward buttons when I had bought a mouse with them. These buttons should have numbers 8 and 9. I would like to use them in Software Center too. It's a very comfortable way to move in history of visited places.

I have tried these buttons in Software Center 3.1.24.1 in development version of Ubuntu Natty. They haven't worked.

Setting as Confirmed, as multiple users have confirmed this, with software-center 3.0.8 and 3.1.24.

Bug is not fixed.

Oneiric 64-Bit up-to-date
USC 5.0.1.4
Unity 3D in VirtualBox
Mouse: Logitech MX 518

Problem 1
When clicking on a category that has no sub-categories like 'Accessories' or 'Fonts' mouse-back-button-click will highlight the entry over which the mouse currently is instead of bringing me back to the USC main page.

Problem 2
When in a category with sub-categories like 'Developer Tools' and clicking the mouse-back-button when the mouse is over a sub-category icon nothing happens (no back-to-main-action is preformed).

Problem 3
When in a category with sub-categories like 'Developer Tools' and clicking the mouse-back-button when the mouse is over a 'Top Rated Developer Tools' item it acts like a left click and opens the top rated item instead of preforming a back-to-main-menu action.

(That problem is tracked in bug 871810.)
