I need to use

REPORT ... PREVIEW NOWAIT SUMMARY

command.

Report will show without detail lines. However, when I click to the Print
button in Preview toolbar, detail lines are also printed !

Is it possible to fix this bug: remove detail band programmaticaly from
copy of report if summary printing is required or is there some other solution.

My users like modeless reports created by REPORT NOWAIT SUMMARY However, they
want also to print them.
