Hmm. I'm running Gnutella0.56 and have been having similar problems, to the extent I've become a bit disillusioned with Gnutella (0.56 is my first experience with it)

I've just tried installing and running Gnotella, version 0.73, but although it looks pretty, has lots of nice features and seems to work better than Gnutella, it crashes within the first couple of searches with an "overflow" run-time error.

Any recommendations of decent clients?
