Thanks Vijay.
I had actually experienced this problem with the traditional
NI driver as well.  Not so for you?
Another thing, after playing with it some more, I realized
that if I go above a certain finite number in
SamplesPerTrigger that it will let me acquire. i.e. its not
just limited to low values and INF, but rather there is a
specific finite window in which it won't let you acquire.
