"Other Software" pane scrolls to top after un-checking box

[Alex]

When unchecking or checking a box in the "Other Software" tab, the contents in the tab always scrolls to the top. It also occurs when a checkbox is checked, then the authentication popup opens, and then the user clicks "Cancel" in the box.

This bug makes it very difficult to select or deselect multiple items because one has to scroll down every time.
