Fred, I have experienced the exact same problem. My VNC speed over my cable modem drops on the order of 30x when I enable ZA. I too feel like I'm on dial-up connection when I have VNC+ZA active concurrently.
My short term solution is do one of the following: 1. Shut off ZA while I'm using VNC -- I have a Linksys Firewall/Router between the PC and the cable modem, so ZA is my second line of defence. 2. Use the browser version of the viewer by opening up http://<machine_name>:58xx where xx is the session number. -- This works, but a) I experience about a 50% speed hit (understandable, I suppose, given the HTTP and java overhead -- still better than the 97% speed degradation of the regular viewer with ZA on!), b) limited to 8 bit color (unless I'm doing something wrong), and c) copying and pasting is a little awkward, since you seem to need an intermediate clipboard, so each copy/paste step becomes a copy/copy/paste operation. My home PC is running Win98. My office laptop is running Win2K. I did a test earlier this week with the laptop running ZA, while connected to the office network, and while connected to the office network from the external side of the VPN. Both worked; no ZA/VNC speed hit. This weekend, I'm going to try the laptop from home. If that works, I may take the plunge and upgrade the home PC to WinXP (I've got enough crud on my home PC that it's overdue for a clean re-install anyway). Alternately, I'll try some of the other firewalls, and see if they can co-exist with VNC.
