Good call! Though not exact, that's sort of what happenned. The fact that it started at the time my ISP lost power seems to be coincidence (what are the odds?). Much digging and gnashing of teeth led to the discovery that Zone Alarm Pro, after many months of working perfectly, suddenly started blocking most of the packets going to and from Trillian. It did this on its own, with no change in settings, and there's a mystery! It also started, a few hours later, blocking messages from Sonork, as well. I deliberately added Trillian, and the subnet it operates on, to the Trusted Zone in ZAP, then removed and re-added the program itself to the list of apps permitted to access the Internet. Rebooting a couple of times changed nothing, but when I shut down both Trillian and ZAP manually, then cold-started the server, it went back to operating smoothly again as it always had before. Problem solved, though not the mystery of why it happenned, or perhaps more importantly, why it had always worked before without any special settings in ZAP.:eek: "How many times do I have to flush before you go away?" - Megan Forbes, on Management (12/5/2002)
