   PIX crashing debug pixel
  I am trying to debug a pixel shader for volume rendering.  PIX always crashes when I select a fragment to debug.  Any ideas?  I am using the March SDK version.   
  I noticed that if I turn off the D3D debug runtime in the DX control panel, then it works.  Can anyone confirm that this is necessary?   ;  Well programs that run fine in debug w/ no leaks or what not regularly give me unexplained crashes in PIX, so I can only assume it's riddled with bugs.   ;  First of all I'd suggest downloading the August 2008 SDK. I haven't installed it yet, but the readme talks a lot about PIX changes.Secondly, I'd like to ask what GPU you're using. I've had this problem with Intel 915 on my subnotebook, but not with NVIDIA or ATI desktop machines. If you can see this on a more up to date chip (and with the latest SDK), that might help Microsoft recreate the problem on their side.
