I think the possible problem with zonealarm though is the screen updates. In the program itself is a running total of throughput, and the icon in the tray keeps having to be changed. This is all expensive in the terms of processing. In fact, as I am aware, anything to do with putting anything onto the screen is the hog. I will post here what Zonelabs say about it, if they respond. They may say they are aware, and that I should download the latest version.
It's funny though that it doesn't happen with Laplink over tcpip. It could be something in VNC that is just creating so much traffic that zonealarm can't keep up. Mind you, I think that laplink is only in 16 colour (4 bit) mode. Regards, Dave Colliver. ~~ All I ask is a chance to prove that money can't make me happy.
