I wanted to post this as a possible solution for folks who are having lock up, "appcrash", or fatal exception errors when using Vegas on a Vista platform. I have the 64 bit home professional version. I have a Gateway LX6200 system - Quad core with 8 gig of ram. (brand new).
The symptoms were these: All of my programs (particle illusions, bluff titler, photoshop, sound forge, swishmax, xara 3d) worked perfectly on my system - no problems whatsoever. However, I was getting constant crashes using Vegas 8.0B or 8.1. The symptoms were always slighty different. Sometimes it would shut down completely by itself. Sometimes I would get the dreaded "fatal exception" error.It always happened seemingly after a certain amount of time elapsed. I spent several hours troubleshooting - ran ram memory test (everything ok), reloaded Vista, reloaded vegas - still crashed.
What I finally found was the problem was my video card! I have dual monitors and when I purchased the pc I also bought a Vision Tek ATI Radeon 512meg DDR2 dual video output card (I think it was an HD 4650). Updating the drivers did not help. If I used the built in vga video connector on the Gateway PC with 1 monitor everything worked great with vegas - no crashes.
I took the ATI Radeon card back and exchanged it for a Nvidia GEforce 9500 GT 1 gig DDR2 (for the same price!) Now everything works fine.
Wanted to pass this along in case someone out there is pulling their hair out.
