I've run into a serious problem when applying packages in IP (current version) on Vista (Hone Premium), it is screwing up my app preferences.
My start menu defaults have gotten messed up, I no longer get the second line of text for the internet and email items (should be IE and Outlook), see pic for what I mean...
When I go into the set associations option, I get the following problem with all the programs that could take the default (IE, firefox, outlook, live mail, windows mail, opera)
This happens any time I apply a package, and if I don't catch it in time with system restore, the only way I've been able to undo this is by a complete OS reinstall.
