I have recently experienced exactly the same problem. I first noticed it when I changed to the 2.6 Pro version, so I thought it was some glitch. But i have recently upgraded to the 2.7.3 version with absolutely no improvement. In the past month or so the number of hits on any search is down by at least 90%. Additionally, before this problem began, when I logged on to Limewire it would show the 1600 files I'm sharing in about 30 seconds. Now the songs are added at a rate of about 1 every five seconds or so. I have to be connected for over an hour to register the complete list of shared files.

I have tried running Limewire with nothing else open, but it makes no differrence. And everyhting else on my computer is running perfectly. (ever since I changed to OSX, which is the most stable OS I have ever used, on ANY platform)

Anybody with ideas?
