Update Manager has unusual checkbox behavior between group and individual checkboxes.

[Jeff Johnson]

Update Manager lists 'Other updates (Google, Inc.)' as the group and 'The web browser from Google' as the only item in that checkbox group. Starting with both checked, if I check the item ('The web browswer...') it is unchecked, but the group remains checked. Then if I uncheck the group, the group becomes unchecked, but the item is checked.

Sometimes if one is checked and not the other, I need two clicks to get it to change checkbox state.
