OK, figured this out Trevor.  I forgot that I have a frontScript  
menuPick handler that does some stuff which could result in the  
datagrid being updated.  I have a global that controls some of that  
stuff and once I set it appropriately, all works perfectly.  Thanks  
for putting me on the right path.

Still trying to track down the other problem with doub display of data.
