Hmm.  Both the monitor window and acquisition loop use 5-second GPIB
timeouts, so they should theoretically behave the same.  What is the exact
error message it's giving you during acquisition?

Are you using double precision, and/or a large sample size relative to the
sampling interval?  I don't recall the particulars but I did see some
timeout issues depending on how much processing the Wavecrest box was being
asked to do.
