ok i set my update to download and let me choose when to install. now the yellow shield comes up saying its d/ling but goes away when wanting to install. i can only install by turning the computer off. i think i caused it by saying i didn't want to install the update and it asked if i didn't want notification of 'these' updates again. i said not thinking it meant the particular update. i think it meant updates in general.

thanks in advance
