Often when I arm the 19th track on Vegas 4 beta, the system completely locks up then shuts down. Doesnt matter if I start from one or start from track 24, once there are 19 of them it locks up...
havent tried yet with input monitoring turned off, but I will
Doesnt happen in vegas 3

could be system specific:


P4 2.4ghz
2XRME HDSP9652
3XRME ADI-DS
