Thanks for the response, Jon. Before I posted my original message tried the following:

DO WHILE thisform.oCRViewer.IsBusy
WAIT WINDOW 'Retrieving data...' TIMEOUT 0.2
ENDDO

The IsBusy property's status never changed and my app went into an infinit loop; which leads me to this question: what's the control busy doing? Is the IsBusy property even the right property to watch for loading the report's data? Will DOEVENTS refresh the CRViewer control so that VFP can see the property's status change?
