Major help needed with 4.9

[jrme15]

I recently upgraded Limewire from 4.8 to 4.9. Limwire is the only p2p that I use and I love it. However, after I upgraded I noticed that I would occassionally be unable to connect to the internet. Neither one of my browsers would connect to any site, but Limwire 4.9 would continue to run. I also do not lost my internet connection, it is just fine. The new version of Limewire is java based, so I reinstalled java and firefox but the problem persisted. I began to cruise Limwire's support forums to find that dozens of others were having the same problem but there are no answers as of yet. I uninstalled Limewire, but if my computer sits for a period of time w/o use, the browsers will not connect again. However, if i restart they work just fine again. I am completely at a loss as to what happened. It doesn't seem to be a big problem as much as a minor annoyance I'd like to remedy.Limewire has offered no solution, and none of the few suggestions others have made in the forums have made any difference. I have all updates and patches for my system. I run Norton Av 2004, Zone Alarm pro version 6,firefox, IE6, and xp sp2. If anyone can offer up any answers or suggestions I would be incredibely grateful.
