I don't think it's a beta issue. I've been having this problem with 2.4.4 also.

Both uploading and downloading. I'll be downloading files (slow, but they're downloading! ) and all of a sudden a bunch of them will drop to 0 KB/sec. Sometimes all of them, but that's usually when for some reason all hosts drop off and new ones start connecting. (That's kinda weird, too.)

Anyway, sometimes downloading files will drop to 0 KB and stay there. Sometimes it even says "Downloading from 3 hosts" and will still sit at 0 KB.

Is that just a fluke of Gnutella? Or a LimeWire bug?
