Stops running for no apparent reason?

[jarvis24]

The regular 2008 version (and prior versions) are not intended to be run on Vista. We have a v2010 beta designed for Vista (as well as XP and Windows 7) if you would like to try it.

Just wanted to add in case it helps anyone that I've been using v2008 in windows XP without any problems. Recently I experienced the same problem--DirectRT stops running without an error--and it seems to be due to incorporating time contingent skip patterns into my input files using the !meta column. Without !meta commands I haven't experienced this problem.
