I haven't run Bearshare on 64-bit Vista or XP for awhile now. I could never get it to run stable on a long-term basis. The server it runs on now is 32-bit XP, running as an Ultrapeer, sharing about 50,000 files, and it will run for two weeks or more with no attention from me.

The general problem I had was "resource creep". It would continue using more and more RAM, until it would max out and crash after 5 or 6 days. The screen problem sounds more like a video issue...?

Cheers
