Well, I shut down Zone Alarm a moment ago to see if it made any difference in Firefox. No other programs have shown any connections problems in several days. Firefox is slow on the net though and images on pages, especially pages with lots of content, often don't load. I end up reloading the pages in order to see everything. Eventually, nothing will load in Firefox at all. Closing the program and reopening it seems to fix this though, at least for a while. These are recent events, however. I've rebooted again and we'll see what happens. I don't know of anything I've changed that would cause the connection problem that affects all programs to disappear. It seems that sometimes when I reboot things behave better than others. I'm still not certain it has nothing to do with Zone Alarm either. It just seems less likely now.
