I dl the last build (20061116) and my freezing problem stop with the pitch increase. Once in a while theres little glitches but still its a big improvment.
Thanks to whoever arange this.
I still can't play my 48kHz normaly(without a pitch increase). I posted a bug report and Jonas closed it cause it was a similar problem to FS#4924 bug.
Anyway I would realy like to be able to follow the evolution of the resolution of this problem so if anybody have infos please let me know.
Thanks again
