Well, I have several applications where I throw a lot of data to Excel via
DDE (in one case the results of a 32000 point fft) and excel takes the
data and does a lot of processing with it, and then returns.  It works
just fine.  VEE patiently waits until Excel has finished.  Perhaps VEE
uses 99% of processor time because you are not asking the computer to do
anything else; after all, you  don't want VEE  running at half speed just
in case something else wants some processor time.  I have never had a
problem printing from Excel while VEE is running in the background doing
data acquisition.
