analog output range change (PXI 4461) & continous generation?

[BenYL]

I shouldn't have spoken so fast - my VI still doesn't work. I accidently left "Allow Regeneration" on, which I can't use.

Here is what I am talking about. In the attached, the analog output will only output the waveform once, even though it gets a new waveform every loop. Why?

I should have included the VI file, though I realize people can't run it without a DAQ card, and with the analog output physically connected to one of the analog inputs.
