NIS 2013: Security Alert dialog boxes take 1+ minutes to be displayed


After upgrading from NIS 2012 to 2013, Norton's Security Alert dialog boxes take over a minute to be displayed.   This makes using NIS brutally slow.

Compare this to NIS 2012, where these dialog boxes were presented instantly.

(yes you can turn off these notifications but this is an important feature of NIS that I use all the time).

Also, as with NIS 2012, these dialog boxes are queued up, and the delay occurs with each item.  So even if you quit the application, you're stuck with waiting 8, 9, 10 minutes as each dialog box is presented.

A fix for this would be appreciated.
