In the Destroy Event of the form, you should do

This.oReport = NULL
This.oCrystal = NULL

>>The question is this, what is the best way to close the viewer and release the report? We've tried a couple of different things, like set the .oCrystal and .oReport properties to .NULL., but if the report has parameters the CR "Enter Parameter Values" dialog appears. If we release the report shouldn't the report, and its parameter requirements, be gone?
