Even with it only taking advantage of one of my cores, it never reached a maximum load on my core, so I suspect that your suspicions are spot on, Mr. Hippo.I am pretty sure most of the instability comes from the software not being optimized properly.
Granted that it only runs on 1 core ( reason why it's not intensive, at all) and perhaps is not fully taking advantage of whatever connection speed you have but I could be wrong about the latter.
