Sound bugs on loading screens and loot crash

I experienced two major bugs.

1. On loading screens, the sound goes on and off. Sometimes I hear my character being hit and killed by mobs during the loading time, but when I appear in the new area, he is full life. I also have the common "map file" bug when I try to tp on new aeras in act 2. I fixed it by the "--nosound" tip and it works, but it's annoying to have to play without the music. I'm on Windows Vista 32 bit.

2. Sometimes, in group, when we kill a boss, the client crashes. I think it comes from the large amount of items which drop at this time. Could it be possible to lower it ? Most of them are trash ones.
