jquery latest nightly and CS4 crash

I have not been able to open the latest jquuery nightly build
(1.3.3pre) in Dreamweaver CS4 (64bit Vista).
The program crashes every time I open the file, or another page that
includes the file. I have no problems with the same files on CS2
(XP).
Has this happened to anyone else? Does anyone else with CS4 want to
double check?
Thanks in advance,
mike
