the x64 never quits and is completely stable. 32-bit quits if I do not interact with it (it has done this in every build), after a render, during a render now (which is really getting to be old), during playback, while loading, while connecting (decoupled, VE Pro instances fully loaded). the crash reports for these various crashes varies. I can't get a handle on what doesn't like what; one reports points to this, another points to that. in the same scenario there could be various threads which crash it.
the *during render* crashes now have this one consistent feature, EG: 10/10/11 7:11:58 PM [0x0-0x157157].com.vsl.viennaensemblepro[3517] DoRender: output stream format does not match ioData.mNumberBuffers. 10/10/11 7:11:58 PM [0x0-0x157157].com.vsl.viennaensemblepro[3517] *** process 3517 exceeded 500 log message per second limit - remaining messages this second discarded ***
when it quits during absolutely no interaction with it, which it's doing far more often recently (this one is a fact of my life for a LONG time, in all sorts of scenarios; I do think it has to do with elaborate GUIs within VE Pro, but I cannot nail it down by attrition):

tt doesn't seem like it's holistic, as I said x64 is COMPLETELY stable.
