GW 2012 sp3. We upgraded over the weekend from GW 8.0.2. The client has been upgraded on only 12 users so far. 10 of the installs were good. The other 2 take a considerable time to open. It takes at least 90 seconds to open any size email. It also takes another 90 seconds to close the email. Each of the 2 users were using the GW 8 client for at least 2 days at normal speeds. It was only when the 2012 sp3 client was introduced that the problem cropped up.
