I recently downloaded the service pack 2 and have had nothing but problems since. The techies tell me that zonealarm pushed me down on the desk and held me while microsoft gave it to me hard and deep.
my wife will fix it but she's pretty busy right now.
In my office we are not touching service pack 2 till the IT people can do more testing on it; good enough for me, I'm not downloading it at home till they are happy with it at the office.
