>In launching a 'report form someform preview' via a button on my form, should I define a window to display the previewed data then release it and give control back to the form? Thats what I did but it gets lost on the way and doesn't seem to work. Has anyone done this before?

The REPORT FORM someform PREVIEW has it's own window. Just invoke
the REPORT FORM someform PREVIEW and on your next line of code type,
thisform.refresh()
