our users have the problem that the notes client is closed with NSD when surfing on different websites. It is not reproducable but happens quite often (1 or 2 times per day).
I could provide some NSD-Logs, but didn't find a way to add it to my post :-)
We use Notes 6.0.2CF2 and Domino 6.5.4CF2. Or clients are Windows XP Pro SP2.
The problem is also seen on Notes 6.0.4 and with Domino 6.0.4
