 Analog input waveform data channels occasionally swap when ...

Analog input waveform data channels occasionally swap when  using
analog trigger on NI 4552 board with "AI Waveform Scan (waveform)" vi.

I'm using the "AI Waveform Scan (waveform)" vi in labview version 6.1
in combination with an NI 4552 DSA board to acquire and display 4
channels of data.  Analog input is triggered using the "analog"
trigger setting of the vi.   Occassionally, (approx. one in 50
triggers) I've observed that the waveform data channels will
erroneously swap, one becoming four, two becoming three.  No error is
reported by the vi, or by any of its sub vis.  This swap doesn't occur
if any other trigger type is selected.  What is causing this swap?
